    Great Producr

    When you get your package you’ll think the bottles are small for the price. Then you’ll find that a small amount (about a dime sized portion of each product-I have shoulder length hair) is all it takes, so it will go a LONG way. The shampoo lathers very well, the conditioner leaves your hair feeling soft and both have a pleasant fragrance. You will notice that your hair is thicker, even before drying! Once you’ve fully dried and styled it, your hair will be thicker, not dramatically so but definitely noticeable. After having tried so many products in the past and been disappointed I was skeptical of this one, as I now am about most every product that is promoted to give your hair thickness, even if it has rave reviews. My sister, however, recommended this line and I thought, why not try it. I am glad I did and would highly recommend it. I’ve stared the subscription service to have the product delivered every 3 months, and this alone says a lot for me!

    Adds body to baby fine hair without weighing it down

    I have baby fine hair that I like to wear spiked, in order to do this I need a thickening spray. I discovered Boldify products a few months ago and they are now my go to product. The thickening spray gives my fine hair body and when blow dried it stands up where I want it to.

    Noticeable Results

    I have been using the shampoo and conditioner for about a week now, and I can definitely see and feel a difference in my hair. It is thicker and more manageable. I am very pleased with the results and will definitely be putting these on my reorder list. Recommended.
