by Did you know that 66% of dermatologists suggest using dietary supplements for better skin, hair, and nails? As we get older, our body makes less keratin, a key protein for these areas. This is why keratin supplements are helpful.
They can make your hair stronger and your nails look better. Studies show these supplements really work. This article will explore the benefits of keratin supplements, how they work, and how much to take. We’ll also talk about possible side effects and how to choose the right supplement for you.
What is Keratin and Its Role in the Body
Keratin is a protein that helps keep our hair, nails, and skin strong. It acts as a shield against harm from the outside world. This protein is also key in making the outer layer of our skin and in the growth of scales, feathers, and claws.
The human body has 54 genes that make keratin. These genes are on chromosomes 12 and 17. They help create different kinds of keratin, which are important for our health.
As we get older, our body makes less keratin. This is why we might need to add keratin to our diet. It helps keep our hair shiny and our nails strong.
- Keratin keeps our skin healthy.
- It’s essential for hair growth.
- Keratin’s properties can change, affecting its role in our body.
Keratin is not just for our skin and hair. It’s also in our internal organs. This shows how important it is for our overall health. People have used keratin for medicine for a long time.
| Type of Keratin | Location | Primary Function |
|---|---|---|
| Alpha-keratin | Hair, skin, nails | Structural integrity |
| Beta-keratin | Scales, feathers | Protection, waterproofing |
| Soft keratin | Internal organs | Flexibility and resilience |
Understanding the Importance of Keratin for Hair Health
Keratin is key to hair structure, making up about 90% of each strand. This protein is vital for hair strength and health. Since keratin is in 65% to 95% of hair fibers, it’s essential for hair’s resilience and life.
The keratin benefits for hair go beyond just strength. Keratin treatments can make hair smoother and shinier. They can also boost hair’s tensile strength by up to 40%, reducing frizz and drying time, especially in humid weather.
There are many keratin treatments available, like salon procedures, keratin oil treatments, and hair masks. But, some treatments contain harmful chemicals like formaldehyde. It’s important to choose safe treatments for your hair’s health.
Keeping enough keratin in your hair can prevent brittleness and dullness, common with aging. Keratin deficiency can slow hair growth by slowing down the keratinization process at the follicle. So, supplements can help improve hair health.
Eating foods rich in keratin, like eggs, fatty fish, and leafy greens, supports healthy hair. Knowing how important keratin is for hair health shows its crucial role in having vibrant and strong hair.
Keratin Supplement Benefits for Hair Growth
Keratin supplements are getting more attention for their benefits in hair growth and health. They usually have a mix of ingredients to make hair stronger and look better. Knowing the science behind these benefits helps people choose the right hair care products.

Studies show keratin supplements can really help hair grow. They found that certain supplements with keratin and vitamins can make hair much healthier. People using these supplements saw their hair get stronger and lose less over time.
How Keratin Affects Hair Strength and Appearance
Keratin is very important for hair health. Supplements add keratin to hair follicles, making hair stronger. Biotin and zinc are key in this process. Biotin helps make hair thicker and healthier. Zinc keeps hair strong and prevents it from thinning.

Effects of Keratin on Nail Strength and Appearance

Potential Side Effects of Keratin Supplements
Keratin supplements are popular for making hair and nails stronger. But, it’s important to know the possible side effects. Some people might experience thick, rough skin or stomach problems. This often happens when they take too much, not knowing the right amount.
Another big worry is formaldehyde in some keratin treatments. The American Cancer Society says formaldehyde is a carcinogen. The FDA warns it can cause eye problems, headaches, dizziness, and sore throats.
Some keratin products have too much formaldehyde. They can have up to 1.4 percent, way over the safe 0.2 percent. Knowing these risks of keratin supplementation helps users make better choices.

| Salon concentrations during treatment | Ranging from 0.08 to 3.47 during blow-drying; 0.08 to 1.05 during flat-ironing |
To avoid side effects, watch how your body reacts to keratin supplements. Don’t take more than what’s suggested. Getting advice from a professional about keratin products is also smart, especially those with formaldehyde or other harmful chemicals.
