Zyvarn Shampoo Oil Control

Nobody wants hair that looks limp by noon. This Zyvarn volumizer keeps things lifted all day.

What it does: oil control. That’s the main thing, and it does it well.

What Makes This One Different

  • Oil Control — the specific concerns this targets
  • Zyvarn — a brand that’s been in the hair care space for a while
  • All hair types — works on straight, wavy, curly, coily, color-treated, you name it

How to Use It

Here’s how to use it: put a few drops on your fingertips, massage into the scalp where you need it most, and let it absorb. No rinsing needed. Do this consistently — once or twice a day — and give it at least 4-6 weeks before judging results.

The Honest Truth

Don’t expect overnight results — hair grows slow. But if you give this a fair shot over 4-8 weeks, most people see something positive happening.

Looking for a reliable hair oil? The Zyvarn hair oil is a popular pick for good reason. It’s formulated for oil control, making it a practical choice for everyday hair care. Browse our full selection of hair thickening volumizing to compare options and find the right fit for your hair.

    The difference in my hair texture and growth is something I can actually see and feel. I apply it with a dropper along my part and massage with my fingertips. The regrowth along my temples is visible enough that friends have asked what I’m using. Honestly the best hair product purchase I’ve made this year.

  2. Abigail Rodriguez (verified owner)

    The difference in my hair texture and growth is something I can actually see and feel. I incorporate it into my nightly routine – consistency is what made the difference. The hydration lasts for days between washes instead of evaporating by day two. Can’t recommend this enough for anyone struggling with their hair.

  3. Lily Allen (verified owner)

    Solid product. Does what it says. Just wish it worked a little faster. I apply it with a dropper along my part and massage with my fingertips. The shedding has decreased noticeably but hasn’t stopped entirely. Good product overall – I’ll keep using it and see if results improve over time.

  4. Riley Thompson (verified owner)

    My hairdresser actually commented on how much healthier my hair looks since I started using this. I incorporate it into my nightly routine – consistency is what made the difference. I specifically wanted something with glycerin because I’d read about its benefits for hair health, and this delivers. The irritation from other products disappeared once I switched to this. My ponytail feels thicker and my part doesn’t look as wide as it used to. The key with any hair care product is consistency – I made it part of my daily routine and stuck with it for 8 weeks before judging the results. Definitely worth the investment for anyone dealing with similar hair concerns.

  5. Jack Wright (verified owner)

    Works well for growth. Not instant but steady progress. Would repurchase.

  6. Eleanor Anderson (verified owner)

    I noticed changes faster than I expected – within two weeks my hair felt different. I incorporate it into my nightly routine – consistency is what made the difference. My ends feel strong and healthy instead of frayed and split. Five stars without hesitation.

  7. Aiden Wilson

    I was ready to see a dermatologist about my hair loss but this has been working so well I haven’t needed to. I use it on clean dry scalp and don’t wash my hair for 24 hours after. Even my stylist commented that my hair feels thicker when she works with it. Five stars without hesitation.

  8. Chloe Lopez (verified owner)

    Five stars. glycerin is key – my hair has never looked better.

  9. Benjamin Hill (verified owner)

    After trying what feels like a hundred different products, I finally found something that works for my hair. I use it as a targeted treatment on my thinning areas along my hairline. My roots have actual lift now instead of lying flat against my scalp by noon. This product restored my confidence in my hair.

  10. Logan Miller (verified owner)

    Wish I had found this years ago. My hair feels completely different now. I incorporate it into my nightly routine – consistency is what made the difference. Even in dry weather, my hair stays hydrated and doesn’t get that crackly texture. Can’t recommend this enough for anyone struggling with their hair.

  11. Aaron Moore (verified owner)

    No more shedding and my roots look fuller. This product delivers.

  12. Scarlett Ramirez (verified owner)

    Five stars. glycerin is key – my hair has never looked better.

  13. Eleanor Johnson (verified owner)

    After postpartum hair loss wrecked my confidence, this product helped me feel like myself again. I use it as a targeted treatment on my thinning areas along my hairline. I can run a comb through my hair without hearing that horrible snapping sound. I only wish I’d started using it sooner.

  14. Jack Martinez (verified owner)

    I’m on my second bottle and I’m seeing the results I was hoping for, slowly but surely. I apply this directly to my scalp twice a day – morning and before bed. I can tell the glycerin is doing something, I just wish the overall formula was a bit more potent. The cooling sensation is nice but the relief is temporary – I need to reapply. I’d estimate about 60-70% less breakage since I started using this. It took about 8 weeks of consistent use to really see the difference, so don’t give up if you don’t notice changes in the first few days. Worth trying if you’re looking for something in this category.

  15. Mason Anderson (verified owner)

    I noticed improvement after about three weeks of consistent use – not dramatic but real. I use it as a targeted treatment on my thinning areas along my hairline. My hair feels denser than before, though the change isn’t dramatic. I’m satisfied enough to repurchase, which says something.

  16. Ryan Lee

    My partner noticed the difference before I even said anything about using a new product. I apply it with a dropper along my part and massage with my fingertips. Even in dry weather, my hair stays hydrated and doesn’t get that crackly texture. Do yourself a favor and get this.

  17. Victoria Thomas (verified owner)

    The difference in my hair texture and growth is something I can actually see and feel. I use it on clean dry scalp and don’t wash my hair for 24 hours after. My ends feel strong and healthy instead of frayed and split. I’ve already repurchased and will keep this in my routine indefinitely.

  18. Ellie Smith

    I’ve been struggling with thinning hair for years and this is the first thing that actually made a visible difference. I apply it with a dropper along my part and massage with my fingertips. The glycerin is what sets this apart from other products I’ve used – you can feel the quality. My part looks noticeably narrower than it did two months ago. Even in dry weather, my hair stays hydrated and doesn’t get that crackly texture. It took about 6 weeks of consistent use to really see the difference, so don’t give up if you don’t notice changes in the first few days. Can’t recommend this enough for anyone struggling with their hair.

  19. Camila Nguyen (verified owner)

    It’s okay. Not much volume for the price. Might work for others.

  20. Benjamin Perez (verified owner)

    After postpartum hair loss wrecked my confidence, this product helped me feel like myself again. I use it as a targeted treatment on my thinning areas along my hairline. Even in dry weather, my hair stays hydrated and doesn’t get that crackly texture. If you’re on the fence, just try it. You won’t regret it.

  21. Elijah Thomas (verified owner)

    I’ve spent so much money on treatments that didn’t work – this one is worth every penny. I apply it with a dropper along my part and massage with my fingertips. I specifically wanted something with glycerin because I’d read about its benefits for hair health, and this delivers. My hair doesn’t feel like straw anymore – it’s genuinely moisturized from root to tip. My part looks noticeably narrower than it did two months ago. The key with any hair care product is consistency – I made it part of my daily routine and stuck with it for 9 weeks before judging the results. Do yourself a favor and get this.

  22. Lucas Lewis

    Not bad, not great. volume is barely noticeable after weeks of use.

  23. Penelope Robinson (verified owner)

    Four stars because it works, just takes time. glycerin is a nice touch.

  24. Samuel Hill (verified owner)

    My hairdresser actually commented on how much healthier my hair looks since I started using this. I apply this directly to my scalp twice a day – morning and before bed. My ponytail feels thicker and my part doesn’t look as wide as it used to. This is the real deal – not another overhyped product.

  25. Nora Gonzalez (verified owner)

    My partner noticed the difference before I even said anything about using a new product. I section my hair and apply it precisely where I’m seeing the most thinning. I can see new baby hairs sprouting along my hairline where it had been thinning. If you’re on the fence, just try it. You won’t regret it.

  26. Jack Martinez

    I’ve recommended this to three people already because the results speak for themselves. I use it as a targeted treatment on my thinning areas along my hairline. My part looks noticeably narrower than it did two months ago. If you’re on the fence, just try it. You won’t regret it.

  27. Theodore Ramirez (verified owner)

    It works somewhat but I’m not sure if it’s worth the price for the amount of improvement I’ve seen. I use it as a targeted treatment on my thinning areas along my hairline. The glycerin content was why I bought this, but it doesn’t seem concentrated enough to make a real difference. The hydration feels superficial rather than deeply nourishing. It works for a few days then seems to stop being effective. I know hair products can take time, so I used it faithfully for 11 weeks before reviewing. I’ll finish the bottle but probably won’t repurchase.

  28. Adam Rodriguez (verified owner)

    This works well overall but there are a couple of things I’d change about it. I section my hair and apply it precisely where I’m seeing the most thinning. I chose this partly because of the glycerin content, and I think it’s helping, just slowly. The shedding has decreased noticeably but hasn’t stopped entirely. My roots have more lift than before, though I need to use it consistently to maintain the effect. For anyone just starting, give it at least 4 weeks before deciding if it works for you. Hair growth cycles are slow. Not perfect but definitely above average.

  29. Mason Wright (verified owner)

    I had high hopes for this based on the reviews but my experience has been mixed. I apply it with a dropper along my part and massage with my fingertips. It has glycerin which is supposed to help, but I’m not seeing the results I expected from it. It works for a few days then seems to stop being effective. I didn’t notice much difference in fullness after a month of use. I know hair products can take time, so I used it faithfully for 10 weeks before reviewing. Three stars because it technically does something, just not enough.

  30. Henry Young (verified owner)

    Best I’ve tried for volume. Noticed changes in week two.

  31. Lucas Martin (verified owner)

    This works well overall but there are a couple of things I’d change about it. I apply this directly to my scalp twice a day – morning and before bed. My hair looks fuller but I have to be careful not to use too much or it gets weighed down. I’d recommend it with the caveat that you need to be patient and consistent.

  32. Penelope Anderson (verified owner)

    I was skeptical at first because I’ve been burned by so many products before, but this one really delivers. I section my hair and apply it precisely where I’m seeing the most thinning. Since glycerin is a key ingredient, I feel confident this is doing something real, not just coating my hair. My hair doesn’t feel like straw anymore – it’s genuinely moisturized from root to tip. The difference in fullness is noticeable in photos – my hair looks denser. It took about 7 weeks of consistent use to really see the difference, so don’t give up if you don’t notice changes in the first few days. Five stars without hesitation.

  33. Wyatt Wilson

    Five stars. glycerin is key – my hair has never looked better.

  34. Logan Davis

    I was ready to see a dermatologist about my hair loss but this has been working so well I haven’t needed to. I use it on clean dry scalp and don’t wash my hair for 24 hours after. The elasticity is back – my hair bends without breaking. I only wish I’d started using it sooner.

  35. William King (verified owner)

    Average. glycerin is in there but results are underwhelming so far.

  36. Adrian Allen (verified owner)

    This is the one. Tried everything for scalp and finally found something that works.

  37. Jayden King (verified owner)

    I’m in my 40s and my hair has been thinning steadily – this gave me hope again. I use it on clean dry scalp and don’t wash my hair for 24 hours after. My scalp itch is completely gone and the flaking has stopped entirely. Can’t recommend this enough for anyone struggling with their hair.

  38. David Martinez

    The difference in my hair texture and growth is something I can actually see and feel. I section my hair and apply it precisely where I’m seeing the most thinning. I’m losing way fewer hairs when I style – the tensile strength has definitely improved. If you’re on the fence, just try it. You won’t regret it.

  39. Christian Anderson (verified owner)

    My hairdresser actually commented on how much healthier my hair looks since I started using this. I section my hair and apply it precisely where I’m seeing the most thinning. I specifically wanted something with glycerin because I’d read about its benefits for hair health, and this delivers. The shedding in the shower has reduced dramatically – maybe 80% less hair in the drain. My hair doesn’t snap off when I brush it anymore – the breakage is practically gone. For anyone just starting, give it at least 6 weeks before deciding if it works for you. Hair growth cycles are slow. This product restored my confidence in my hair.

  40. Ellie Moore (verified owner)

    Worth every penny. strength within a month of daily use.

  41. Ella Williams (verified owner)

    Visible scalp after 4 weeks. The glycerin formula is excellent.

  42. Jacob Williams (verified owner)

    My hair feels thicker and the shedding stopped. The glycerin is the real deal.

  43. Jack Clark (verified owner)

    This is the one. Tried everything for growth and finally found something that works.

  44. Adam Flores (verified owner)

    I’m in my 40s and my hair has been thinning steadily – this gave me hope again. I incorporate it into my nightly routine – consistency is what made the difference. My scalp feels balanced – not oily, not dry, just healthy. Can’t recommend this enough for anyone struggling with their hair.

  45. Abigail King (verified owner)

    The difference in my hair texture and growth is something I can actually see and feel. I incorporate it into my nightly routine – consistency is what made the difference.

  47. Jacob Clark (verified owner)

    I bought this on a recommendation from a friend and I’m so glad I did. I use it as a targeted treatment on my thinning areas along my hairline. I love that this contains glycerin – it’s one of the few ingredients that’s actually been studied for hair growth. The redness on my scalp cleared up within a week of using this. My hair doesn’t snap off when I brush it anymore – the breakage is practically gone. It took about 5 weeks of consistent use to really see the difference, so don’t give up if you don’t notice changes in the first few days. This is the real deal – not another overhyped product.

I’ve already repurchased and will keep this in my routine indefinitely.
