I'm barely on here much but BOY! I have to tell you ladies about B12. I started taking one sublingual tablet of 5000 mg and I'm seeing abundant hair growth! I wasn't even taking it for my hair. I bought it for heart health. My hair is growing faster than normal and my eyebrows need to be done already. I not fond of the later part (lol) but geez, I have to add something else to my arsenal now. I hope this thickens my hair up too. Have you ladies had thicker growth with this?
