More hair in your brush or shower drain

Start with the Actsyl-3 Hair Serum, our daily serum with Redensyl 3% and Capixyl 2%. It's the core of every Actsyl routine and is made for shedding that follows weight loss, GLP-1 medications, a new baby, perimenopause, or a stressful stretch. Prefer no scent? Actsyl-X is the same formula, unscented.

Hair that looks finer at the part or crown

Add the Actsyl-3 Shampoo and Conditioner. They're sulfate-free and made to clean the scalp without stripping it, so the serum goes onto a clean base.

Tangles, snapping, and breakage when you brush

Add Actsyl-D Detangler, a leave-in mist that loosens knots and protects hair from heat styling, so fewer strands break off.

Sparser lashes or thinner brows

Actsyl-L Lash Serum and Actsyl-V Eyebrow Serum bring the same peptide approach to lashes and brows.
