Rave review: “I have fine naturally grey hair which is glossy and shiny as a result of this oil. There is a number of regrowth also which is great.” Avoid fragranced products. Products with extra fragrance may perhaps diminish the effectiveness of the rosemary oil or bring about skin irritation. https://allhealthmarket.com/product/health-and-beauty-2/hair-care/5-10-15-20pcs-biotin-fast-oil-hair-serum-baldness-hair-thinning-regrowth-treatment-liquid-anti-hair-loss-for-women-men/
