Excessive hair shedding in females can be caused by a variety of factors, including genetics, aging, autoimmune disease, hormonal changes, stress, and infections that damage the skin and hair follicles. While chemicals in bleaches and hair styling products can potentially weaken hair, they are not involved in female pattern baldness, which is the most common cause of hair loss in women. However, some chemicals in hair care products can cause itching, irritation, and other problems. Here are some ingredients that may cause hair loss or other hair problems:
-
Formaldehyde: Some people report noticing shedding and hair loss after exposure to formaldehyde, although there is no scientific research that shows a direct link between the two.
-
Sodium laurel sulfate (SLS): This chemical, which produces lather in shampoos, can strip hair of essential oils, break down protein essential for hair health, and halt growth. Products containing SLS may also contain sodium chloride (table salt), which can cause dry, itchy scalp and encourage hair loss.
-
Preservatives: Formaldehyde and parabens such as methylparaben and propylparaben are often included in hair care products to prolong shelf life. These chemicals can affect hormonal balance and encourage hair loss.
-
Irritants: Ingredients that cause scalp inflammation and allergic reactions can exacerbate hair loss and make thin hair dry, brittle, and lifeless. Products containing diethanolamine (DEA) and triethanolamine (TEA) can destroy hairs keratin and cause scalp irritation. Fragrances and artificial colors can also cause problems.
Its important to note that excessive intake of certain nutrients, such as vitamin A and selenium, can also contribute to hair loss. However, more studies are needed to establish the relationship between these nutrients and hair loss. If you are experiencing excessive hair shedding, its best to consult a healthcare professional to determine the underlying cause and appropriate treatment.
