Shoppers Say Their Hair Stopped “Falling Out in Clumps” Thanks to This Thickening Shampoo

Thanks to COVID-19 and hormonal fluctuations courtesy of my polycystic ovarian syndrome (PCOS), I go through bouts of intense hair shedding. When this occurs, I don’t simply want one treatment; I want thickening, anti-shedding properties in every step of my haircare routine. I assume such is true for other people experiencing this, too. So begin at the first step and swap out your regular shampoo for Biolage’s highly-rated Full Density Thickening Shampoo. 

There are three products in the Full Density line: a shampoo, conditioner, and leave-in spray treatment. These products take a two-pronged approach to combating thinning hair. First, it improves the health of your strands from the root of the follicle to the end making hair less susceptible to breakage and shedding. Second, it supposedly increases the number of follicles and strands of hair on your scalp. 

The key ingredient in this formula is zinc pyrrolidone carboxylic acid (PCA). Although it doesn’t get as much attention as say rosemary oil, zinc’s scientifically proven hair growth benefits make it a superstar ingredient in this area. One study found that zinc “plays a key role” in reducing several types of hair loss. Another study similarly found that people with low levels of zinc had more severe hair loss. 

So how does Biolage’s zinc-rich Full Density Thickening Shampoo hold up? Very well if the nearly 2,000 five-star ratings are anything to go by. One shopper said it “changed [their] hair completely.” They switched to this shampoo because their hair was “falling out in clumps… and so thin.” After using this Biolage shampoo, however, only a few strands fall out. “[My hair] feels better, grows faster, and is more voluminous.” Another shopper wrote, “it makes my hair smooth… helps it to grow, replenishes and hydrates my hair.”
