    NO MESS! – – 5 of 5 stars

    By Isabella – Size: Regular / Color: Dark Brown

    Very easy to use without the mess. TopSecret is everything it says it is! Works much better than root cover up spray for making hair look fuller. I cannot live without this stuff.

    FANTASTIC! – – 5 of 5 stars

    By Deb – Size: Regular / Color: Dark Brown

    I love this product. My hair had gotten super thin due to a Thyroid condition. I decided to give TopSecret a try and it’s fantastic so far. You can’t even tell it’s not my hair. I will continue to buy this product from now on. I tried some others (Toppik and Bosley) before but didn’t like nearly as much as this.

    AWESOME! – – 5 of 5 stars

    By Jeff – Size: Regular / Color: Medium Brown

    I wanted to do something about my hair which has been getting thinner. I tried Top Secret and it has made a dramatic difference. It looks so natural, my hairdresser had no clue I had anything in my hair and she was standing right over me! This stuff is a life saver. I couldn’t recommend it more!!

    LIFE CHANGER! – – 5 of 5 stars

    By David – Size: Regular / Color: Auburn

    Got this product today and was so excited to try it. I take medications which has cause my beautiful hair to fall out, and left me with a several thin spots. I actually started to cry after the first use when i could see my hair looking full again. Really easy to use and takes only a few minutes to apply. I will never go another day without it.
