I love it; love it, love it- my hair is; thanks to VitaStrand hair vitamins. I'm just about to start my second bottle. I noticed a softness and strength in my hair after about 2 weeks. I frequent my hair salon each week so I'm really enjoyed seeing the difference the vitamins have made. I can see a growth of about 2 ½ inches in length. My hair is coarse and somewhat thick anyway. My new growth noticed in about 2 ½ - 3 weeks after my touch-up. Taking the vitamins early in the day with breakfast allows me to benefit from the fact that I hydrate myself with more water. I noticed I have become thirsty more often, which is a good thing. Thanks again for VitaStrand.
