The 15 Best Hair Growth Shampoos Of 2024, For Every Hair Type

A clean, refreshed scalp is vital to keep the hair follicle in good condition—and by allowing buildup to accumulate, you risk the chance of increased shedding. On the flip side, however, you want to make sure the hair fiber isn't stripped in the process: Dry, brittle hair leads to breakage—putting a halt to any lengthening or fullness goals. 

It's a tall order, finding a shampoo that meets those requirements. Additionally, everyone has their own unique hair types and quirks—like if you highlight your hair, you'll want something that can tend to the color as well.

This brand's cult-favorite hair growth serum has amassed a huge, loyal following thanks to its efficacy. Well, those powerful plant-based ingredients make a star appearance in this gentle shampoo: The micro-encapsulated phyto-actives penetrate the scalp, delivering the nourishing growth-enhancing ingredients. What makes it particularly useful for damaged hair is the vegan silk protein complex that helps smooth and restore damaged strands with continued use. As if that's not enough, wild-harvested marula, baobab, and ximenia oils further condition the hair, too.

While fine hair and thin hair are often used synonymously, there’s technically a difference. Fine hair refers to the diameter of the strand itself, while thin refers to the density (or how many strands you have on your head). So when speaking about the needs of fine hair in particular, you should find formulas that will give hair lift and won’t weigh the style down with too much moisture or heaviness. This shampoo offers a deep clean, lightweight hydration, as well as feeding it antioxidants and biotin—somehow, all in one bottle.

For those who appreciate scents—this juicy one is not to be missed, with light, easy notes of jasmine, red apple, and peach.

Hair growth is influenced by many factors, from your genes to stress, environment, nutrition, scalp health, and the products you use. It's always best to approach any beauty goal from a holistic perspective—so we encourage you to think about all of these variables when crafting your hair care routine. There's no one, single magic elixir that will do it all for you. 

However, as part of that well-rounded routine, a shampoo that encourages hair growth is a wonderful addition. Shampoos play a very important role in hair growth as they are your primary scalp products, and having a clean scalp is high on the list of priorities. 

When you neglect washing the scalp, it can lead to oxidative stress. "This oxidative stress will affect the quality of your hair growth. It happens when you have product, dirt, and oil building up around your follicle opening—which is where your hair grows out of—and that buildup starts to slowly suffocate your hair root," says trained trichologist and hairstylist Shab Reslan. 

So at the very least, shampoos can encourage a healthy environment for hair by making sure the follicles are free of debris. Many shampoos go a step further by adding ingredients that strengthen or hydrate the hair fiber, which won't actively stimulate growth but will care for the strands you do have (and then limit breakage down the line). You can look for things like humectants, proteins, lipids (like from plant oils), castor oil, and antioxidants. 

Finally, shampoos can also infuse ingredients to stimulate growth itself: There's growing research that some plant-based actives (like peppermint oil, rosemary oil, and peptides) may improve growth rate and thickness. 

In short: Shampoos can play a role in hair growth, among many other things. So if growth is your primary goal, absolutely look into one of these options below—but you should also address other factors like nutrition, stress, sleep, etc. 

The primary job of a shampoo is to clean the scalp, so the most important ingredients are going to be the cleaning agents (such as surfactants). But for hair growth shampoos in particular, you’re going to want to look for additional ingredients that stimulate the scalp, feed the skin and follicle nutrients, and protect the hair fiber.

Like we’ve noted, shampoo alone cannot single-handedly fix hair loss. For best results you need a well-rounded hair care routine that supports growth from multiple angles. 

We believe that if you want healthy hair long term, it’s vital to use both lifestyle remedies and high-quality hair products as part of your routine. 

If hair growth is your primary goal, you need to craft a smart routine from top to bottom. That starts with a shampoo, like one of the above.
