3 Signs Your Body Is Craving Keratin (And What To Do About It)

When you think of keratin, you probably picture shiny hair after a salon treatment, right? But here’s the real tea: keratin is so much more than a buzzword. It’s a natural protein your body makes to keep your hair, skin, and nails strong and healthy—basically, it’s your body’s own beauty armour.

But what happens when your body’s running low on keratin? Spoiler: it tries to tell you! Here are three signs your body might be asking for a little extra keratin love—and what you can do about it.

1. Your Hair Feels Weak, Dull, or Breaks Easily

Ever feel like your hair just isn’t itself? Maybe it’s snapping off, looking a bit lifeless, or just not bouncing back like it used to. That could be your body’s way of waving a little flag saying, “Help! I need more keratin!”

What’s going on?
Keratin is the main building block of your hair. When you don’t have enough, your strands can get brittle, dry, and prone to split ends—even if you’re using decent products.

What to do:

• Add more protein-rich foods to your meals (think eggs, fish, beans).

• Try a supplement with functional keratin (like KiriGlow!) to help rebuild your hair from the inside out.

• Use keratin-infused products to give your hair a boost while your body catches up.

2. Your Nails Are Weak, Peeling, or Just Won’t Grow

If your nails are breaking at the slightest knock, peeling, or just refusing to grow past a certain point, you might be low on keratin.

What’s going on?
Like hair, your nails are made mostly of keratin. When your body’s not making enough, your nails can turn soft, thin, or flaky.

What to do:

• Snack on nuts and seeds for biotin and zinc (your nails will thank you!).

• Keep your nails moisturised and avoid harsh chemicals.

• Consider a keratin supplement for that extra boost.

3. Your Skin Feels Rough, Dry, or More Sensitive Than Usual

If your skin’s suddenly feeling a bit like sandpaper, or you’re noticing dry patches and irritation, keratin could be the missing piece.

What’s going on?
Keratin helps your skin stay smooth and acts as a protective barrier. Without enough, your skin can lose its glow and become more sensitive.

What to do:

• Stay hydrated and eat colourful veggies for vitamins your skin loves.

• Use gentle, nourishing skincare (bonus points if it’s got aloe or panthenol).

• Support your body with a supplement that helps keratin production.

What Causes Low Keratin?

Lots of things can slow down your keratin production, like:

• Not eating enough protein or key vitamins (biotin, zinc, vitamin A)

• Stress (yep, it really does affect everything)

• Ageing (it’s normal, but you can help your body out)

• Hormonal changes (think perimenopause or thyroid shifts)

• Over-styling or using harsh products

How to Give Your Body a Keratin Boost

You can’t just eat keratin, but you can help your body make more by:

• Eating a balanced diet with protein, healthy fats, and lots of veggies

• Taking a high-quality keratin supplement (like KiriGlow!)

• Choosing hair and nail products with functional keratin

• Managing stress and getting enough sleep—your body repairs itself overnight!

Bottom Line

If your hair, nails, or skin are looking a bit sad, your body might be craving keratin. Listen to those signs! With a few simple tweaks—better food, smart supplements, and gentle care—you’ll help your body get back to its strong, shiny, glowing self.
