"No smell, no weird texture, clearly largely water based, perfect. After years of using Minoxidil, i kept losing my hair, and had those well known bad side effects on my skin. No side effects at all with the this."

Reviews Summary

Customers say this scalp treatment shows promising results for many users. Many notice reduced hair shedding and new baby hair growth, particularly around the hairline, after consistent use. The lightweight formula absorbs well, though some mention it can leave residue if not washed out. While experiences vary with timing of results, frequent comments note visible changes within 2-3 months of regular use. Some find it works best with morning hair washing, while others adapt it to their existing routines. A few report scalp sensitivity or increased shedding, though most describe it as gentle on the scalp.

I saw some growth
I used this for 2.5 months so far. I do think it has helped with growth although it’s not anything crazy. The residue is a huge drawback though.
