Life saver!
"We had a camper fire and my hair was singed in the process. I tried to find a product that would heal my hair and also make it stronger. Healing Strength Silk Serum did not disappoint. My stylist is in shock as to how quickly it healed my singed hair. It has definitely been a life saver!"
Lanza Strength Products
"Every time I try to use a different product from another brand it always seems to damage my hair. Lanza always keeps my hair healthy, strong, and shiny!"
Formula changes make all lanza products not worth price
"They changed the formula of this and all their products): I no longer will be buying lanza products due to formula changes. They no longer work well and they're way too expensive to be buying when the products are worse than drugstore."
