    I love this stuff

    I love the shampoo, the conditioner and now this serum. My hair has not looked this good in years!!! I will keep trying other products too. I also love the blog tips. I purchased microfiber hair towels after reading your blog about not roughly drying your hair. They work great and were cheap on Amazon.

    Wonderful product!

    I love that this conditioner makes my hair soft, but not so soft that it won’t hold any shape.

    Boldify is the Best!

    My hair has gotten much thinner with age. I have tried so many of the expensive and highly advertised products for thicker hair. Finally, I found Boldify and it's the only product I use now. None of the other products begin to give the same results! Not only is it sulfate and paraben free, it's safe for color-treated hair and really delivers on volume and fullness. Love it!
