6 Essential Proteins For Natural Hair: Strength, Moisture and Shine

There are a few signs your hair shows when it needs a protein treatment and you should be aware of them. The first sign is when your hair keeps breaking and won’t grow past a certain point, even when you’ve been diligent and consistently doing “everything that you’re supposed to” (like washing regularly, deep conditioning, detangling with care, moisturizing, etc). The second sign is if it gets mushy when it’s wet (as if it has been depleted of its “bone structure”). And last but not least, is when your hair doesn’t spring back when you pull it - you can test this by pulling a piece of shedded hair and see if it goes back to it’s original shape.

Protein treatments sometimes get a bad rep, but the truth is that they may be able to assist you in bringing your hair back to life. But the thing with protein treatments is that if you’re not careful, you risk getting a protein overload, which is far form desirable (I speak from personal experience). So don’t go overboard with these treatments opt instead to integrate them slowly into your routine until you find the right balance with moisturizing hair treatments.

A number of protein treatments may assist your kinky, coily or curly hair ingesting back it’s definition when it needs.

1.Hydrolyzed Keratin: A Game-Changer for Coily, Kinky or Curly

What is Hydrolyzed Keratin?

Hydrolyzed keratin is a protein derived from natural sources like wool, feathers or even human hair. This protein undergoes a process called hydrolysis, breaking it down into smaller, more absorbable molecules that can penetrate the hair shaft. This makes it a powerful ingredient for strengthening and repairing damaged hair.

Benefits of Hydrolyzed Keratin in Haircare

  • Strengthens Hair: it fills in the gaps in the hair cuticle, making strands more resilient to breakage.

  • Improves Elasticity: enhances the hair’s flexibility, reducing the chances of snapping during styling.

  • Reduces Frizz: helps smooth the hair’s surface, creating a sleek and shiny appearance.

  • Protects Against Damage: protects the hair from environmental stressors and heat styling.

Tips for Using Hydrolyzed Keratin

  • Use Sparingly: overuse can lead to protein overload, making hair stiff and prone to breakage. Limit the use of keratin-based products to once or twice a month, depending on your hair’s needs.

  • Pair with Moisture: balance keratin treatments with deep conditioning to keep hair hydrated.

  • Patch Test First: some people experience sensitivity. Always test new products on a small section of hair.

  • Follow Instructions: products containing hydrolyzed keratin often have specific usage guidelines to avoid over-processing.

Warnings Associated with Hydrolyzed Keratin

While hydrolyzed keratin is beneficial, excessive use can lead to protein overload. This occurs when the hair becomes too stiff and loses its elasticity. To prevent this:

  • Alternate between protein treatments and moisturizing treatments.

  • Limit the use of keratin-based products to once or twice a month, depending on your hair’s needs.

  • Opt for Leave-Ins: silk protein is particularly effective in leave-in treatments that stay on the hair longer.
