What Our Customers Say
“I’d tried a lot of things for my thinning crown. The EELHOE serum started working around week 10 — my hairdresser noticed before I even mentioned it.”

“Got the growth kit for my husband. Three months in, the thinning spots are filling in. The return policy made it an easy decision.”
Common Questions
Frequently Asked Questions
Everything you need to know about our hair regrowth products and services.
How long before I see results?
Most customers notice visible improvements within 8-12 weeks of consistent use. Hair growth is gradual — patience and consistency are key. Products with Minoxidil may show results in as early as 4 weeks.
Are these products safe for color-treated hair?
Most of our products are formulated to be gentle and safe for color-treated hair. Check individual product descriptions for specific compatibility. Our serums and oils are particularly suitable.
What if a product doesn’t work for me?
We offer a 30-day money-back guarantee on unused products. Email support@howregrowhair.com and we’ll take care of you. We stand behind every product we sell.
Do you ship internationally?
We currently ship to all 50 US states with free shipping on orders over $35. International shipping coming soon. All orders processed within 24 hours.
What active ingredients should I look for?
The most effective ingredients include Minoxidil (FDA-approved), Rosemary Oil, Biotin, Keratin, and Caffeine. All our products are vetted for these proven actives.
Can I use multiple products together?
Yes, many customers combine a serum (targeted treatment) with an oil (scalp nourishment) and a spray (daily maintenance). Our Growth Kits bundle these for convenience and savings.
