Baby hairs at my hairline by week 8

I'd wasted months and a lot of money on a pricey serum that did absolutely nothing. With GROW I noticed less hair in the shower drain by about week 5, and by week 8 there were little baby hairs filling in along my hairline. I actually gasped in the mirror.

Finally one that isn’t greasy

My last hair oil left everything greasy and flat — I had to wash my hair constantly. This absorbs in seconds and my hair still looks clean and full. I put it on in the morning and go.

No scary side effects

I didn't want to risk the side effects you hear about with the pills. This is just a topical peptide serum — my part is filling in and I never had to worry about any of that.

Gentle on a sensitive scalp

Minoxidil left my scalp dry, itchy and flaky and I had to quit. GROW is the opposite — zero irritation, no burning. Taking off a star only because I'm still waiting to see major thickness at month 2, but the shedding is already down.

My ponytail feels thicker

Three months in and my ponytail genuinely feels thicker, and my part doesn't show as much scalp. The dropper targets exactly where I need it so nothing is wasted.

No subscription trap, bottle lasts

Refreshing after my last brand's billing headaches — no sneaky auto-charges, no fighting to cancel, and one bottle actually lasts me the full month. And it's working, which is the main thing.

Less breakage

My hair feels stronger and I'm getting way less breakage and split ends. Lightweight, no smell, sinks right in.

Working but slowly

Being honest — it's week 6 and I see slightly less shedding but not dramatic regrowth yet. Texture and ease of use are great though, so I'm going to keep going for the full 90 days.

Ten seconds in the morning

Easy, mess-free, no residue. I was skeptical after everything else flopped but my hairdresser actually noticed new growth at my temples last visit.

The one that finally worked

I'm a serial hair-serum returner. This is the first that didn't leave my fine hair limp and sticky — it stays full and clean all day. Repurchasing.

Happy so far

Six weeks, noticeably less in the drain and a couple of new baby hairs. No grease, no itch. Would love a slightly bigger bottle but no complaints on results.
