If you think you need to thicken up your locks, a hair thickening shampoo is probably your best bet. Though they might take a while to work (especially if you have particularly thin hair) they are some of the best shampoo and conditioners out there to help you in your quest for a full and luscious mane.

Though thickening shampoo can't treat hair loss on its own, it's a great way to add some volume and rejuvenate your hair if it's looking dull or feeling a bit thin. Pair that with some shampoo for hair growth and you're ready to take on the world (or your daily Starbucks run, at least).

From Viviscal to L'Oreal, there's a wide range of retailers that sell hair thickening shampoos. Most products contain biotin and collagen, which is perfect for thickening hair. If you have an oily scalp, you might want to consider buying a shampoo for greasy hair that also promotes hair regrowth and thickening instead.

Do hair thickening shampoos actually work?

As mentioned before, hair thickening shampoos don't tackle the problem of hair loss, well, head on. It is however a great alternative if you're looking to thicken up fine and thin hair.

Hair thickening shampoos contain ingredients such as biotin and collagen which are scientifically proven to improve and promote hair regrowth in anyone at any age. It also improves the structure of the hair meaning that it's less likely to break in the future and in turn, will look thicker.

Are there cons to using hair thickening shampoos?

Like any shampoo, hair thickening shampoo may cause a build-up of product in your scalp after wash days. Also, if you have a sensitive scalp you may need to check the ingredients of the product you are using as it may inflame and irritate your skin. You might find that your scalp may go dry, and if that happens, we recommend switching to a dandruff shampoo.
