Sulfates
It’s not that sulfates in your shampoo always cause hair loss — it’s that they can dry your hair and cause hair breakage, which looks a lot like hair loss. When your hair is broken, you can see little areas around the scalp that appear broken and the texture of your hair can even feel different. The problem is: sulfates are very common, and very addictive. This is the ingredient responsible for creating a satisfying lather that many of us associate with “clean.”
Try to read your shampoo label and reject anything that contains the words “sodium lauryl sulfate.” There are plenty of sulfate-free shampoo options on the market that are affordable and will make your hair look and feel clean, with or without the lather.
Dimethicone
Dimethicone is a sneaky, tricky ingredient because it can make your hair look amazing — before making it look worse. This silicon ingredient is often added to conditioners, but also some shampoos, and is meant to make your strands look and feel softer and shinier. And some of them work really well, too. The problem is that they are also pore-clogging ingredients. And guess what happens when you clog your hair follicles? The buildup could cause your hair follicle to stop receiving moisture and shed.
There isn’t a ton of substantial evidence though about the harms of dimethicone, but if you are experiencing hair shedding, this may be an ingredient you bypass.
These alcohol types can easily dry out your strands and scalp, which can lead to more hair fallout and split ends.
A better way to go when shopping for shampoos for hair shedding and thinning is to choose those that contain nourishing ingredients known for their ability to boost your scalp’s health. Biotin, saw palmetto, and rosemary oil are all excellent at helping to strengthen your hair follicles and will give your strands the moisture and love they need.
