I bought this shortly after I had my first baby, (Dec 2024) and used it every wash and would mix a few pumps of it in with my shampoo. I wash my hair about every 3-4 days. I started seeing results immediately with the shine and texture of my hair. I then start seeing amazing hair growth after the first 3 months of use! There isn’t much you can do to prevent postpartum hair loss, but this serum gave me new growth and slowed down the hair loss. I also dealt with itchy scalp postpartum and that completely went away with using this serum. I have recommended to many friends and family members!
