After using the Onion & Biotin Hair Growth Shampoo for a period of time, I was pleasantly surprised by how gentle yet effective it is. The combination of onion extract, biotin, rosemary, and tea tree oil creates a powerful natural growth formula that truly nourishes both the scalp and hair strands. My hair feels stronger and looks fuller, especially after a few washes. The shampoo�s sulfate-free and plant-based formula is extremely gentle; I've used it regularly without worrying about dryness or irritation, even with my color-treated hair.One standout benefit is the soothing effect on my scalp thanks to the tea tree oil. It helped calm itchiness and reduced dandruff, which had been a persistent issue before. Unlike many anti-hair loss shampoos, this one does not contain harsh chemicals, allowing natural regrowth to take place while reinforcing hair follicles to prevent breakage.The texture is light, it rinses out cleanly, and the herbal scent is fresh without being overwhelming. A small amount goes a long way. Even though it doesn�t lather abundantly, the cleansing power is evident. This shampoo is suitable for all hair types, and I find it especially helpful for thinning or weak hair.
