Less shedding, more confidence

"Every shower was stressful. I'd watch handfuls of hair go down the drain and feel helpless. Three weeks into using Regen, the shedding slowed. By week 6, I stopped finding hair all over my pillow. By week 9, my temples looked less bare."

My hairline actually came back

"I've tried minoxidil, oils, everything. This is the first thing that worked without making my scalp itchy or my hair greasy. The temples filled in after about 9 weeks. Not magic. Just consistency and patience."

i love this

"I was losing hair in clumps after a stressful year. Tried oils, tried foam, tried everything. This was the first thing that didn't make my scalp itch. I noticed baby hairs along my hairline on day 50!!"

4.8/5 based on +1,000 verified reviews

Three yellow stars on a white background

Mildly skeptical at first. Around week seven I noticed baby hairs along my hairline. Not overnight, but real progress.

Maya P.

Verified

Lightweight, not greasy. Feels like skincare for the scalp. My crown looks denser after 3 months.

James O.

Verified

Neutral scent, easy routine. By month two the thinning near my temples looked less obvious.

Aisha R.

Verified

Bought it on a whim. Smells neutral (thank god, no fake perfume) and easy to apply. Hair feels thicker, not like straw anymore.

Jennifer L.

Verified

My hair feels stronger and I’m shedding less in the shower. Subscribed after my first bottle ran out.

Sofia M.

Verified

Not greasy, absorbs fast. I’ve tried The Ordinary before β€” this feels like the grown-up version. Pricey, but the texture and results are way better.

Jamie K.

Verified

My dermatologist recommended I avoid Minoxidil because of irritation. This serum has been the best alternative. Scalp feels calmer, and I’ve seen noticeable new growth around my part line.

Diane P.

Verified

I don’t usually write reviews, but regen. deserves it. Been using for 3 months, hair feels thicker and fuller. My wife even commented that it looks healthier. That’s all I needed

FAQ

Most people notice less shedding in 3-4 weeks. Visible thickness shows up around week 6-8. Hair growth is slow. Patience pays.

If you're dealing with thinning hair, visible scalp, or post-stress shedding - yes. If you're looking to reverse complete baldness - no. Peptides support what's there and encourage new growth, but they're not miracle workers.

Nope. Fragrance-free means it smells like nothing. You won't walk around smelling like essential oils or chemicals.

If you're dealing with visible scalp, post-stress shedding, or thinning around the temples and crownβ€”this is for you. If you're looking to reverse complete hair loss or grow hair where there hasn't been any for yearsβ€”peptides can't do that. Set realistic expectations. Get real results.
