Finding the right shampoo for your hair type can be tricky. Conventional wisdom suggests the more expensive a product is, the more luxurious your hair will turn out to be. However, with companies like TRESemmé marketing their products as salon quality at an affordable price, the tide seems to be rightfully turning against pricey shampoos, conditioners and other hair tools. 

Suffice to say, you don't need to break the bank to get gorgeous hair. If luxury is something you crave and, crucially, can afford then more power to you but for everybody looking to save a few bucks without sacrificing overall quality, there are plenty of great options on the market you can try out. These are some of the best drugstore shampoos on Amazon in 2021, for all haircare needs. 

Best drugstore shampoos for fine hair

Fine hair can be difficult to manage. Too much product and it tends to feel weighed down and greasy, but not enough and your strands are left parched and dry. Love Beauty and Planet's specially-formulated shampoo for fine hair promises to provide much-needed volume, making hair feel thicker. Lightweight, paraben and sulfate free, this dreamy concoction is also vegan and super gentle. Infused with both coconut oil and coconut water, it works as a thickener and a strengthener, so fine hair is protected while it's being washed.

Elsewhere, OGX's Thick & Full + Biotin & Collagen Extra Strength Volumizing Shampoo is infused with Vitamin B7 (otherwise known as biotin), collagen, bamboo fiber extract, and hydrolyzed wheat protein to give fine hair a real boost. The extra-strength formula is still lightweight, however, ensuring a deep clean without sacrificing body or volume.

Thinning hair is a major concern, particularly as we get older.

Thankfully, Viviscal's Gorgeous Growth Densifying Shampoo is here to save the day with its protein-packed ingredients including biotin, keratin, and zinc. 

Aimed at dry and frizzy hair, in particular, this shampoo cleanses the scalp and hair simultaneously while also promoting the appearance of healthy growth across the board. A refreshing scent, meanwhile, ensures using it never feels clinical.
