I have used so many different hair vitamins over the years, and this is by far the best I have ever used. I even tried a very popular brand to test out my theory of which brand is superior. I did Laced for 3 months straight and was amazed at how much fuller and healthier my hair looked and felt. I then tried the other brand for 3 months straight and my hair gradually returned back to the limp and dull mess it was before Laced. I am now back on my Laced vitamins and am so confident with the quality of the product due to the result of my fabulous mane after taking them for 2-3 months on a daily basis. My skin is even clearer as well!
