    Will repurchase

    I'm on my first bottle and I can say I feel and notice a positive difference in my hair texture and my hair type is 4c Afro textured hair and I suffer from androgenetic alopecia I would have to consistently use this product to truly know it's full benefits the product with the use of others has prevented hair fall and fullness with continued use it should help with retention and growth this product specifically targets hair strands it's not meant for the scalp while there are others that are scalp treatments this product can be added to your leave in conditioners when applying to your hair
