Healthy, shiny hair is every woman's dream, and protein and keratin are among the most popular cosmetic treatments used to achieve healthy hair.
However, their benefits vary depending on the hair type and scalp health, and incorrect use can lead to adverse results.
The Importance of Protein for Damaged Hair
Protein is an essential element in repairing damaged and brittle hair, as it:
- Rebuilds the hair's internal fibers.
- Gives hair a healthier, thicker appearance.
- Reduces hair breakage and hair loss.
- Improves hair elasticity and makes it stronger.
The Role of Keratin in Smoothing Hair
Keratin has numerous benefits for strengthening curly or frizzy hair, giving it a smooth, straight texture:
- Significantly reduces frizz.
- Maintains hair softness even after repeated washing.
- Easier to style daily.
- Provides a natural shine and healthy appearance.
The Difference Between the Benefits of Protein and Keratin
Despite their similarities, each has a specific function that distinguishes it from the other:
- Protein repairs hair from the inside out, while keratin works to coat it from the outside in.
- Keratin is suitable for smoothing hair, while protein repairs damage.
- Protein is used for damaged hair, and keratin for curly or frizzy hair.
Hair Types That Benefit from These Treatments
Not all hair types need the benefits of protein and keratin, as:
- Curly and frizzy hair benefits from keratin.
- Dyed or chemically treated hair may require a protein treatment.
- Natural, healthy hair often doesn't need either treatment and can be damaged by excessive use.

There are cases in which it's best to avoid these treatments to avoid harm, including:
- If you're pregnant or breastfeeding due to chemicals.
- If your hair is very weak or suffers from severe hair loss.

- Scalp irritation.
- Hair loss if misused or overused.
- Damage to hair follicles.
- Allergic reactions to the chemicals present.

Article Summary
