Your Results Timeline

Hair growth takes patience. Here's what to expect.

Week 2–4
Less Shedding
The first sign it's working: less hair in your brush and shower drain. Biotin and Redensyl strengthen existing follicles, reducing breakage and premature hair fall.
Week 6–8
Scalp Health Improves
Scalp feels healthier and less irritated. Improved blood circulation from Caffeine and Niacinamide creates a better environment for new hair growth.
Week 10–12
New Growth Visible
Baby hairs begin appearing along the hairline and thinning areas. Existing hair feels denser and stronger. This is where consistency really pays off.
Month 4+
Visible Thickness
Hair looks noticeably fuller and thicker. New growth continues filling in. Most users see their best results at 4-6 months of continuous use.
