Silicone-based shampoos are popular because they add shine to hair, but over time, they also prevent hair follicles from absorbing nutrients, causing hair to become increasingly dry and brittle, leading to hair loss.
1. Silicone
Dr. Enrizza P. Factor, a dermatologist and member of the Philippine Dermatological Society, said that silicone, which is often found in shampoos, is described as beneficial because it increases hair shine and luster. However, Dr. Factor also emphasized that this substance can prevent the scalp from absorbing essential nutrients, thereby weakening hair follicles, leading to hair loss. "Silicone in shampoos can cause hair loss by coating the scalp, preventing nutrients from being absorbed," she said.
Over time, silicone also accumulates on thicker hair, making it heavier, leading to hair loss.
2. Sulfates
These harsh detergents are a common ingredient in shampoos and conditioners. They're added to shampoos because they strip away natural oils, but they can also leave hair dry, brittle, and damaged over time. Using products with harsh sulfates can make hair loss worse, especially if your hair is already thin and weak.
Most hair experts say sulfates are "one of the most damaging ingredients" found in popular conditioners. Hairstylist Lauren Udoh says the ingredient in conditioners "can also cause scalp irritation and hair loss."
Surfactants like sulfates are used to remove dead skin and excess oil from the scalp. They can cause frizz and allergic reactions to the scalp. Plus, when used over time, they can disrupt hormones," adds Jean Will, co-founder of wig and hair care brand NiaWigs Inc.
3. Sodium Chloride
Sodium chloride is a common ingredient in commercial shampoos, says Yoram Harth, MD, a member of the American Academy of Dermatology and the Hair Research Society. Often used to thicken shampoos and conditioners, it can "cause dryness, redness, and itching."
Harth adds that scalp irritation can "damage hair follicles and cause more hair loss."
Expert Yoram Harth recommends that women with thinning hair or experiencing hair loss avoid shampoos and conditioners containing sodium chloride.
