By Leah Williams •  Updated: 09/23/22

Chemical treatments, sun exposure, heated tools, and diet can all damage your hair. 

The inside structure of your hair, known as keratin, can be damaged by items in your environment that strip away natural moisture.

In that sense, protein treatments can benefit extremely dry and damaged hair by restoring its overall hair structure.

But the central question is whether a protein treatment is actually beneficial for your hair. And if the hair is made up of protein, why do you need protein treatments?

Let’s find out!

Do protein treatments actually help hair?

Yes, protein treatments, if used in moderation, can actually benefit your hair. Below we have listed the key benefits of using protein treatments to improve your hair health and condition.

5 Key Benefits of Hair Protein Treatments

1. Eliminates Breakage and Split Ends

Protein treatments can help banish split ends and eliminates hair breakage. It not only improves the elasticity and strength of hair but also promotes hair growth as protein treatments can make dry and brittle hair break less. 

2. Improves Hair Elasticity

If your hair lacks protein, it stretches more than usual, making it prone to breakage. In that case, protein treatment works by restoring hair elasticity for it to stretch normally and prevent breakage. 

3. Strengthens Hair

As we all know, protein is the building block of hair. So, replacing the lost or damaged protein in your hair can strengthen the length of your strands.  

4. Protects Hair from Damage

Silk amino acids or silk proteins and hydrolyzed wheat protein attach directly to the hair follicle and in turn harden the hair cuticle. This creates a barrier around the follicle which protect the hair from damage when exposed to heat and other environmental factors. 

5. Provides More Luster and Shine

Hair protein treatments works by improving hair elasticity and density and also making your hair strands naturally stronger. As a result, this gives your hair a shinier and healthier appearance. 

What You Should Know About Protein Treatments

Protein treatments are infused with keratin and collagen, which can help strengthen hair, restore moisture, and also shield your natural hair from further damage.

While anyone with damaged hair can benefit from occasional salon protein treatments, results could be better if you use heated tools (in moderation) with it.

Still, remember that protein treatments are not meant to replace shampoo and conditioners – they work well with these products for maximum benefits. Protein treatments are generally meant to be used once a month, but this can vary depending on your hair’s condition.
