The One Pro Therapy Biotin Fortifying Tonic is a professional leave-in scalp treatment formulated to strengthen the hair fiber and promote healthier-looking, more resilient hair. Enriched with Biotin, Pro Vitamin A, and Pro Vitamin B5, this advanced tonic helps reinforce weak and fragile hair while supporting the scalp's natural balance. Its lightweight, fast-absorbing formula refreshes the scalp without leaving residue, making it ideal for daily use.
Developed as part of the The One Pro Therapy Biotin collection, this fortifying tonic helps improve the appearance of thin, weakened hair by nourishing the scalp and strengthening the hair from the roots to the ends. With continued use as part of a complete hair care routine, it helps reduce breakage, improve hair vitality, and leave hair looking fuller, healthier, and stronger. Suitable for all hair types, including natural, color-treated, and chemically processed hair.
For best results, apply directly to a clean scalp after washing. Gently massage with your fingertips until fully absorbed. Do not rinse. Use regularly together with The One Pro Therapy Biotin Shampoo, Conditioner, and Mask to maximize strengthening and conditioning benefits.
