If you're looking to add extra inches while nourishing your scalp, using one of the best shampoos for hair growth is a great place to start. While a fortified cleanser is a single step in the journey to healthier hair, experts say the right formula can make a real difference in the amount of length retention, fullness, and thickness your hair has.

“A good shampoo is designed to clean off excess sebum and product build-up without stripping the hair of its natural oils,” trichologist Kerry E. Yates tells Bazaar . A cleanser that’s both gentle and effective, and contains a blend of conditioning agents and humectants, is extremely beneficial for hair’s elasticity and pliability. “This combination can be hard to find as a lot of shampoos focused on thinning hair can feel drying, leaving the mid-lengths and ends vulnerable to damage,” adds Yates.

Yates says this formula from Jennifer Aniston's haircare line "has a nice blend of scalp cleansers, natural emollients, and ingredients to help support hair elasticity and suppleness," and says it's a "good overall shampoo for all hair types." However, she notes that it contains a surfactant, cocamidopropyl betaine, which she often avoids because it can sometimes irritate.

Infused with keratin proteins, this shampoo helps give the appearance of fuller hair. According to Yates, the staple “Cleanses the scalp while also focusing on the hair, lifting up each individual hair strand to camouflage the appearance of thinning hair,” she explains.
