Sulfates
Sulfates like sodium lauryl sulfate and sodium laureth sulfate are both dangerous ingredients in hair products. Although sulfates help clean dirt and oil out of the hair, they sometimes strip the hair down too much--leaving hair brittle and damaged.
Staying away from shampoos that contain sulfates is a good way to keep your hair healthy and prevent unnecessary hair loss.
Parabens
Parabens are a common shampoo ingredient. but they can cause major hair damage by irritating the scalp. With that in mind, stay away from any shampoos that contain methylparaben, ethylparaben and propylparaben.
Silicones
Finding a silicone-free shampoo is also a smart way to protect your hair from unnecessary damage. Silicones can dry out the hair, leaving it brittle and more susceptible to damage.
With that in mind, finding a shampoo that eliminates these ingredients is a good way to protect your hair from avoidable fall out.
