Ingredient Talk: Is Hydration or Protein Better for Your Hair?
October 17, 2023
For many, hair care styling and maintenance are crucial parts of a beauty routine. Even if you keep your hair short or throw it up into a sleek bun most days, you’ll still want to take care of your hair and scalp for healthy strands. Moisture, hydration and protein are key components needed for healthy hair and with the latter, there seems to be a lot of confusion about its role when it comes to tresses.
To decipher between protein versus hydration hair needs, we tapped a roster of hair experts to give insight into keeping hair moisturized and healthy. Below, hear from hairstylists Rogério Cavalcante of The Second Floor Salon, Kevin Kelly, founder of Kevin Kelly Luxe Extensions, Jennifer Korab, owner of the Renaissance Salon & Spa and Alyssia Dotson, Alterna Haircare Creative Team Lead Stylist.
What is Hydration for Hair?
Hydration for the hair is all about keeping water in your strands and having it penetrate deep for your mane's overall health. You can add hydration to your hair through the regular use of deep conditioning treatments, hair oils or leave-in conditioner, confirms Cavalcante. These products add moisture and help keep hydration in the hair cuticle for healthier hair.
Sometimes hydration is confused with moisture, says Dotson, however, they are two (subtly) different things. “Hydration primarily focuses on keeping your hair well-watered, whereas moisture encompasses the broader concept of maintaining a balance of both water and oils. This harmonious balance is what you should strive for to keep your hair healthy and well-moisturized.”
What is Protein for Hair?
Protein and hair are truly best friends, mostly because hair is made up of protein. The protein that is in your hair (along with your skin and nails) is called keratin, our experts confirm, and is an essential component for maintaining healthy hair. “Keratin is a protein that gives hair its strength, elasticity and texture,” says Korab.
This type of natural protein is not the exact same as the protein found in hair care treatments or products (however, both repair, strengthen and smooth strands). Once the protein in your hair is damaged, it can’t be replicated until strands grow back. Protein found in hair care is usually listed as keratin, wheat protein, soy protein, collagen, amino acids or oat flour on product labels.
What Hair Types Benefit from Protein and Hydration?
All hair types need protein and hydration to retain hair strength for smoother, more resilient strands. However, some hair types benefit more from protein and hydration and need them both for overall hair health.
If you have a standing salon appointment to change up your hair color every season or constantly reach for heating tools to style your hair, you’re ultimately causing damage to your hair and depleting protein in strands. Damaged hair needs protein treatments (and hydration), confirm our experts, to repair hair for healthier strands.
When it comes to hydration, Cavalcante and Kelly recommend those with dry hair, especially coily and curly hair, keep extra hydration in strands to combat frizz and maintain moisture in the hair. According to the American Academy of Dermatology (AAD), thick, curly hair types are most prone to breakage and dryness, compared to other hair types. These hair textures struggle to retain moisture, confirms Dotson, which can lead to dryness, frizz and breakage. “Regular hydration is essential for maintaining softness and preventing these problems,” she says.
When Should You Use a Hydration or Protein Treatment?
You should use a hydration treatment any time your hair is feeling extra dry or starts to frizz, no matter how much moisture you give it. Hair that needs hydration often deals with flyaways, strands that easily tangle and undefined curls or waves. When you touch dehydrated hair, it’ll feel drier and have a less shiny appearance.
To minimize damage, keep your hair hydrated constantly through the daily use of styling products like the L’Oréal Paris Elvive Hyaluron + Plump Moisture Plump Serum or with hydrating shampoo and conditioners like the L’Oréal Paris Elvive Hyaluron + Plump Hydrating Shampoo and L’Oréal Paris Elvive Hyaluron + Plump Hydrating Conditioner, which won’t strip your hair and keep hydration locked in with the infused hyaluronic acid.
If you have damaged hair then you need to add protein to your hair care regimen. By keeping the right balance of protein in your hair, you can minimize signs of damage like hair breakage, frizz and stringy hair. Cavalcante recommends those with damaged hair and healthy hair use a protein treatment. “For those with healthy hair, a protein treatment every two weeks works well, but if your hair is damaged, a weekly treatment can make a significant difference,” he says.
Can Hair Have Too Much Protein or Hydration?
While you may be tempted to coat strands in a protein or hydration treatment in an attempt to repair hair quickly, you’re actually overloading strands with these nourishing ingredients. In general, too much of a good thing is true with protein and hydration. “Too much hydration or protein could cause hair to become very frizzy and frail and break off,” Kelly says.
Protein overload and buildup occur when you go overboard with a treatment and hair is left feeling rigid and weighed down. Excessive hydration can also make hair feel overly soft and susceptible to breakage. Dotson says, “Achieving the right balance between hydration and protein treatments is essential. It's crucial to tailor your hair care routine to your specific hair type and texture to maintain healthy and beautiful hair.”
How to Fix Protein Overload and Hydration Overload?
The easiest way to address protein overload is to cut back on protein-rich hair care products. “Focus on moisturizing your hair with hydrating shampoos, conditioners and [hair] masks. A clarifying shampoo can also help remove excess protein buildup,” recommends Cavalcante. If you’re dealing with hydration overload, he recommends switching to lighter, water-based products and avoiding over-conditioning. It’s always wise to follow the directions of the specific product you’re using to avoid over-using anything that could lead to protein overload or too much hydration in hair.
