Breakage mostly happens between washes — brushing, tying, blow-drying, all the small friction that adds up. This leave-in stays in the hair to absorb that. Arginine and hydrolysed soy protein reinforce the weak points along the strand, and citric acid smooths the surface so the brush slides instead of tugging. Use it just on the worst areas or all over; either way it doesn't need rinsing, so the protection stays put all day. After a couple of weeks there's visibly less hair in the brush and ends look blunter rather than wispy.
How to Use:
- Apply to damp hair, concentrating on fragile or damaged areas, leave it in without rinsing, then style as usual.
