10 inches of virgin brown hair. I've never blow dried, straightened, dyed, permed, or curled my hair. I wash my hair twice a week, sometimes once a week depending on how it's feeling. I used Pureology shampoo and conditioner for about a year and a half and I have been using Matrix Shampoo and Conditioner for the last year. I don't drink alcohol, smoke, or vape. I take the Pure Synergy Vitamin B Complex once a day and I have taken that for the last two years. I also take a Saw Palmetto supplement. I am a singer and drink tons of water everyday, I don't drink soda or coffee. I eat lots of leafy greens and cruciferous vegetables and meat 3-4 times a week. I also drink a pea protein based protein supplement everyday.
