Advantages and Side Effects of Keratin Hair Treatments

Keratin hair treatments have become a go-to solution for many seeking to transform frizzy, unmanageable hair into smooth, silky strands. This salon treatment offers a myriad of benefits, but it's crucial to understand both the pros and cons to decide if it’s right for you. Whether you’re in Melbourne or Sydney, knowing what a keratin hair treatment entails can help you make an informed decision for your hair health.

What is Keratin Hair Treatment?

A keratin hair treatment is a chemical process that uses keratin, a natural protein found in hair, skin, and nails, to smooth and straighten hair. This treatment involves applying a keratin solution to the hair and sealing it in with heat from a flat iron. The result is smooth, frizz-free hair that can last for several months with proper care.

Types of Keratin Treatments

Keratin treatments come in various forms, tailored to different hair needs. The Brazilian Blowout is famous for its strong straightening effect, though it contains formaldehyde. The Cezanne treatment is a safer, formaldehyde-free option that uses a different blend of ingredients to smooth hair. Goldwell Kerasilk treatment requires more time but delivers intensive smoothing benefits using heat activation.

Benefits of Keratin Treatment

1. Smooth, Shiny Hair

Keratin treatments penetrate the hair follicles, filling in porous areas with a keratin solution. This results in a smooth and shiny finish, giving your hair a polished, salon-quality look that lasts.

2. Better Manageability

With reduced frizz and smoother hair, keratin treatments make your hair more manageable. This means less time spent blow-drying and styling, and more time enjoying your sleek locks.

3. Long-Lasting Results

A well-done keratin treatment can last up to six months with proper care. Using sulfate-free and sodium chloride-free products will help maintain the smoothness and shine of your hair for longer periods.

4. Soften Curls

For those who prefer to keep their curls but want to reduce frizz, keratin smoothing treatments like Cezanne and Goldwell Kerasilk are ideal. They soften and smooth each strand without eliminating natural curls.

5. Hair Growth

Keratin treatments can enhance hair health by adding a protective protein layer. This reduces breakage and split ends, indirectly promoting hair growth by maintaining stronger, healthier hair.

Side Effects of Keratin Treatment

1. Hair Breakage

While keratin treatments can strengthen healthy hair, they may cause breakage in already weakened or damaged hair. The high heat used during the treatment process can exacerbate this issue, leading to breakage and split ends.

2. Chemical Reactions

Some keratin treatments contain chemicals like formaldehyde, which can cause discomfort or allergic reactions in some individuals. Those with asthma or other respiratory conditions may be particularly sensitive to these chemicals.

3. Poor Quality Treatments

Using low-quality products or undergoing the treatment with an inexperienced stylist can result in poor outcomes. These treatments may contain harmful levels of formaldehyde or other chemicals, leading to chemical burns or other adverse reactions.

Keratin Treatment FAQs

How Long Does Keratin Treatment Last?

The effects of a keratin treatment can last from a few weeks to up to six months, depending on the treatment type and your hair's individual characteristics. With proper care and maintenance, you can extend the longevity of the treatment.

Can Keratin Treatment Cause Hair Loss?

While keratin treatments can strengthen hair and reduce breakage, they may cause hair loss in some cases, especially if the treatment is applied incorrectly or on already damaged hair. It's essential to consult with a qualified stylist and follow proper aftercare instructions to minimize the risk of hair loss.

Does Keratin Treatment Affect Hair Colour?

Keratin treatments should not significantly alter your hair color. However, if your hair has been previously color-treated, there may be some fading. Using a color-safe shampoo and conditioner can help preserve your hair color after the treatment.

Why is My Hair Still Frizzy After Keratin Treatment?

Frizziness after a keratin treatment can occur if the treatment is not applied correctly or if the hair is exposed to excessive humidity or moisture shortly after the treatment. Using sulfate-free hair care products and avoiding heat styling can help maintain smoothness.

Is Keratin Treatment Suitable for Thin Hair?

Keratin treatments can be beneficial for thin hair, as they can help strengthen and add volume to the hair shaft. However, it's essential to consult with a stylist experienced in treating thin hair to ensure the best results and minimize the risk of damage.

Can I Tie My Hair After Keratin Treatment?

It's best to avoid tying your hair into tight hairstyles, such as ponytails or braids, immediately after a keratin treatment. This can cause unwanted bends or kinks in your newly smoothed hair. Instead, opt for loose hairstyles to maintain the treatment's effects.


Keratin hair treatments offer a promising solution for those seeking smooth, silky locks.

However, it's essential to understand both the benefits and potential side effects before undergoing treatment.
