I’ve used it for years. No problem!
USING FOR OVER A YEAR. THINK IT DOES THICKEN HAIR AFER SHAMPOO.
I am 80, and still somewhat vain about my appearance. Approximately age 65-70, my cowlicks started balding. I assumed it was my dna, my father balded early as did his aunts. It was always so embarrassing to try to weave my hair over the pink scalp crossing through my blonde hair. After 3-weeks of using all of your restoration products, my hairdresser noticed fuzz; it soon became a nice undergrowth that covered my cowlicks and gave me an abundance of hair for styling. Cortex Expander and Amp Me Up have made my hair thick and luxurious. It is so exciting! My salon is amazed, and I tell them they should be offering your products to their clients.
I am very excited about the product works for me.five star
