Just finished my third bottle of this @dove scalp serum and already repurchased another. I’ve been using this for probably close to a year now. I love how it has made my hair feel especially my scalp as someone who has scalp psoriasis. I feel like my overall scalp health has improved and my sparse spots are definitely fuller from when I started. Main Active Ingredients- B3/ Niacinamide - reduced hair loss, prolongs anagen growth phase, enhances blood flow, hydrates the scalp Zinc- prevents thinning, balances scalp oil production, crucial for keratin production so helps prevent breakage.
