The Scruples Biotin Onion Shampoo is an incredibly stimulating shampoo designed for those with damaged and thinning hair strands. This shampoo is infused with Biotin and Onion Extract to provide your hair and scalp with a multitude of different benefits! Biotin is like the building block of hair and plays a crucial role in keeping hair strands healthy. Biotin helps to increase hair follicle growth as well as keratin production, which helps to promote thicker, fuller, and healthier-looking hair strands. Onion Extract is rich in antioxidants, which help to stimulate the blood circulation in the scalp, supporting hair growth and reducing the amount of thinning hair. Onion Extract provides the hair with sulfur for keratin production and also helps to deeply nourish hair follicles. It additionally contains antioxidants and has antimicrobial properties that help reduce scalp inflammation and protect against free radical damage. The Scruples Biotin Onion Shampoo helps to support a healthy scalp environment and support hair growth, while leaving strands with a citrus garden scent, not actual onions!
