Ingredients that may cause hair loss
One of the potentially dangerous ingredients common in shampoos are sulfates. Sulfates basically make the shampoo lather. There are two major types of sulfates: sodium laureth sulfate (SLES) and sodium lauryl sulfate (SLS). SLS is said to be the more harmful type as it is a carcinogenic. SLES is only potentially dangerous in large amounts.
Another ingredient that may be hair loss-causing is paraben. Parabens are hormone disruptors and environmental carcinogens. Formaldehyde is present in some products like an anti-frizz as it works to straighten hair and make it more manageable. Although it is allowed in very small amounts in products, formaldehyde may still have short-term (e.g. irritation, nausea, asthma attacks, headaches, etc) and long-term (e.g. neurotoxicity, leukemia and cancer) effects.

First, you have to know whether you are truly losing a lot of hair. Conduct a hair pull test whereby you grab a handful of hair and pull. If you can take more than 10 hairs, then you are indeed suffering from hair loss. Every day, we lose 50 to 100 hair shafts.

If you have recently switched to a new brand of shampoo and since then, have noticed your hair falling out excessively than it used to, then you can suspect your shampoo for it. Look at the ingredients. Take a switch to your old shampoo that you’re suitable with and see if your hair is no longer falling out. Otherwise, other factors could come into play.

You can also try going to a salon and ask the stylist to wash your hair after a trim. It could be your new shampoo if your stylist won’t notice massive hair fall.  In this case, you can ask the stylist as to what type of shampoo is appropriate for your hair.  If your hair fall is not natural, then it’s time you consult a hair specialist for it could be a symptom of another condition.
