Less shedding in the shower

I used to see a lot of hair in the drain every wash. After about 3 weeks of nightly use, there's noticeably less fallout.

Baby hairs coming back

Around week 5 I started seeing tiny new hairs along my temples and hairline. My ponytail feels thicker when I tie it.

No greasy residue

I was scared it would leave my scalp oily, but it disappears completely. I can apply it in the morning and still style normally.

My hairdresser noticed first

She told me my crown looked denser before I even mentioned I was using anything. That was the best confirmation.

Easy habit, wish bottle was bigger

Takes 30 seconds before bed and doesn't stain my pillowcase. Only giving 4 stars because I finished it in 3 weeks with daily use.

More confidence in photos

I used to avoid photos from above because my part looked so wide. Now I don't even think about it.
