Overview
Men seeing early thinning or a receding line get a matched wash and conditioner built around biotin, caffeine and rosemary oil. Saw palmetto, zinc and probiotics target the scalp, while castor and argan oils condition the lengths.
Two steps from one line means the actives reach the scalp in the wash and the conditioner, with a clean, herbal scent from rosemary, basil, sage and lavender. It is cosmetic support for thinning, not a medical regrowth product.
Who it's for
Daily washing for men noticing fine, brittle strands or early receding, including color-treated hair. People who dislike herbal scents or need a prescription-grade product should pass.
Pros and cons
- Shampoo and conditioner in one set
- Sulfate and silicone free
- Safe on color-treated hair
- Leaping Bunny certified and vegan
- Bottle sizes not listed
- Herbal scent may not suit everyone
- Hair loss benefit not clinically shown
Performance notes
Any scalp benefit depends on how long the shampoo stays on before rinsing, since the actives work through contact. Without sulfates the lather is milder, and the argan and castor oils in the conditioner govern how soft the lengths feel.
