My part looks noticeably fuller after about a month. The tingle lets you know it’s working.

Postpartum shedding was brutal. Three months in and the baby hairs along my hairline are coming back.

Doesn’t strip my color and my scalp finally stopped feeling itchy and flaky by week two.

I’ve tried every thickening shampoo out there. This is the first one where my stylist noticed the difference.

Frequently asked questions

How long until I see results?
In clinical testing, scalp condition improved within 2 weeks of consistent use. Most people see visibly fuller-looking hair in 4–8 weeks — hair grows on a cycle, so give it a full bottle.
Can I use it on color-treated hair?
Yes. The formula is free of parabens, silicones, and sulfates, so it won't strip color. It's dermatologically tested and safe for all scalp and hair types.
Is it safe to use every day?
It's gentle enough for daily use. For best results we recommend 3–4 washes a week, paired with the Thickening Serum on non-wash days.
