We all know that haircare involves far more than simply choosing the right best shampoo and conditioner, particularly when you have natural hair. When you have textured hair, it's important to choose moisturizing leave-in conditioners, shampoos for natural hair, hair masks, and scalp treatments so that your hair can look its bounciest and healthiest. Because hair strands are made entirely of protein, it's also important to take in enough of this nutrient—ideally through your diet, but also through a topical protein treatment for natural hair. 

"Hair is naturally made of protein, so when your hair lacks it, it's important to restore it with the protein it needs," says Kiara Brumfield, a chemist and cosmetologist who works in Product Development at Universal Beauty Products. "Protein treatments are a great way to repair hair strength and prevent breakage, which, in turn, can contribute to hair retention."

She adds that protein treatments can be the perfect pick-me-up for tired, over-treated, or damaged hair. 

"Everyone needs protein but those who often chemically treat their hair, use excessive heat, or cause damage from constant style manipulation may need protein treatments more often," she explains. 

Protein treatments are especially great products for natural hair, curly hair, and high porosity hair, particularly if you're experiencing dryness, frizz, dull hair, or weighed-down curls.

"Healthy natural or curly hair, with the proper amount of protein, has great elasticity, shine, and strength," she says. "But if there is a lack of protein it can cause curls to loosen and hair strand breakage, affecting the overall appearance."

If you're new to the world of protein treatments, you may be wondering when, how, and what to do from here. So I asked Brumfield to break down all there is to know about protein treatments—what to use, how to use it, and when. 

When and How To Use a Protein Treatment

Incorporating new products into one's well-established hair wash routine is never easy or intuitive. Luckily, many protein treatments are created with ease of use in mind, so adding a new step can be quick and seamless rather than complicated and time-consuming. Brumfield breaks it down for us.

First, she says, "Make sure your hair is clean and free of any build-up before applying a protein treatment." Otherwise, "your hair will not be able to absorb any proteins from the treatment."

When in doubt? "Protein treatments should be applied by following the manufacturer’s instructions," she advises. So if the bottle says it should be applied to clean, build-up-free hair, be sure to cleanse before use. Then leave the treatment on for the time specified in the product's instructions, and wash out. 

As for how often you should break out your go-to protein treatment, Brumfield advises, "Protein treatments should only be used when your hair needs it. Using protein treatments when your hair doesn’t need it will not have any benefits for your hair. You should only use protein treatments if you experience symptoms like breakage when combing, loose curl definition, or low elasticity."

Unlike deep conditioners, which can be incorporated weekly or even bi-weekly into your routine for maintenance, these treatments are more like triages for your curl woes.
