My experience taking biotin for over a year. My hair has been flourishing. I prefer the gummies but if you want to start small and work your way up you can always start with the oil and then switch to the pills/gummies. My husband has been taking them as well he prefers the pills and says the gummies have an aftertaste lol. I noticed the fastest results taking them orally. I linked the some of the ones I’ve tried below #biotin #biotinhair #hairgrowth #locgrowth #locs #Sisterlocks #microlocs #naturalhairgrowth #greenscreen
