Keratin Treatment vs Rebonding: Which Removes Frizz Best for Curly Wavy Hair?

Published on Oct 19, 2021

Curls Curls Curls - many of us who have them find ourselves having a love-hate relationship with our curly hair. Yes, curls are beautiful because they add volume and personality to our hair but, in reality, they are a difficult mess to manage in hot and humid Singapore.

It is no wonder many of us turn to straightening options to temporarily or permanently remove those curls. 

What are those options? No need to scour hair salons for them. Here's a detailed explanation of what straightening options are available in Singapore. 

Keratin Treatment

The second form of straightening treatment is Keratin. This is a non-permanent straightening option that works by wrapping a layer of keratin around the hair

Four Steps of Keratin Treatment

The process goes like this:

  1. Pre-treatment removes surface build-up and prepares the cuticle so the keratin can penetrate the hair
  2. The hydrolysed keratin that penetrates the hair cuticle strengthens it by wrapping itself around the hair
  3. Heat is then applied to the hair to seal the layer of keratin

Under this category, you might be overwhelmed by the amount of variations there are. We have an article explaining the difference between Hair Botox, Brazilian Blowout and traditional Keratin Treatments here so read on if you want to find out more.

Which is the better option to defrizz curly hair?

Frizzy Curly Hair

Rebonding is the best anti-frizz treatment for you if:

1. You don't like curly hair and want to permanently eliminate your curls


This is best for women who have decided that their curly hair is unmanageable and just want voluminous straight hair!

2. You want to easily sculpt and style your curls

Don't like your curly hair but don't want stick straight hair either? No problem.

Stylists can combine perming and Rebonding techniques to give you straight mid-length hair and curly ends. The most common styles include C-curl or S-curl Rebonding.

C Curve Rebonding is one of the most popular types of Volume Rebonding because it is convenient and easy to manage. It basically involves Rebonding the top and perming the ends to create C-shaped curls that curve inwards. To accommodate this style, the cut is heavy and does not have many layers.

Like Volume Rebonding that looks more like a perm than Rebonding, S Curve Rebonding Rebonds the top and perms the body and the ends to create S-shaped curls. The cut has many layers to create the effect of piles of soft curls. 

S Curve Rebonding has a more romantic, feminine look while making sure that the top of your hair is manageable! The curls are also the most defined among the different types of Volume Rebonding available.

3. You want your hair to have volume but feel light 

Keratin Treatment coats the hair with keratin. While this helps to reduce frizziness, it also weighs the hair down, reducing volume on the whole. If your hair is already very fine and sparse, this may cause your hair volume to reduce quite a bit. 

Rebonding on the other hand allows the stylist to control hair volume by tweaking the level of straightness or curls within the hair. A good stylist can include some gentle curls to make the hair feel voluminous without making it heavy. 

This is what Focus Hairdressing did with their Blowout Perm using henna dyes!

4. You're looking to colour your hair or do additional chemical treatments in the future

As Keratin Treatment coats the hair, it makes it harder for colour to penetrate. Doing a colour soon after Keratin Treatment also causes the keratin to fade off faster. 

If you love to change your hair colour or do hair retouches often, you may want to opt for Rebonding rather than Keratin Treatment as the latter will not affect your future hair colours.

5. You want a budget-friendly option that doesn't require too much maintenance

While Keratin treatments are on the rise, prices for Keratin Treatments still tend to be higher, especially when you consider that Keratin Treatment tends to require you to go back to the salon faster than Rebonding (3 months)

In addition, Keratin Treatment requires you to use the corresponding Keratin Shampoo to ensure that the effect lasts 3-6 months. Read more about the best Keratin Shampoos to use after your Keratin Treatment. Using straighteners or swimming often will also affect how fast the keratin fades. If you don't want to have to worry about all that, Rebonding is possibly the more hassle-free option.

6. You want a 100% Formaldehyde-free straightening option

Only formaldehyde-free Keratin Treatments are allowed in Singapore. Unfortunately, some formaldehyde-free keratin still releases low amounts of formaldehyde with the application of heat. 

When inhaled, such fumes may cause allergic reactions and even cancer after prolonged exposure. This issue has been quite controversial in the industry, even led to lawsuits in the US.

For pregnant women or ladies with sensitive scalp, Rebonding is still definitely the safer choice.

Keratin Treatment is the best anti-frizz treatment for you if:

1. You love your curls but want it defrizzed

As you can see, Keratin Treatment need not make your hair super straight.

2. You want your hair to look shiny and glossy after the treatment

Keratin Treatments wrap a layer of keratin over your existing hair. This adds a layer of shine and gloss that you won't get to see with Rebonding!

If you are looking for something more than just glossy hair and frizz-free hair, check out NOV Treatment that is being offered by selected salons like COVO Japanese Hair Salon. This treatment uses a hydrogen ion shampoo that can help to neutralize any toxins existing in your hair cuticles making your hair firm and healthy.

3. Your hair is very damaged

Rebonding itself breaks existing hair bonds so that it can be resculpted. This causes additional damage that some bleached hair may not be able to endure. For highly damaged hair, Keratin Treatment may be the last resort as they coat the hair and make it at least possible for you to comb through!

4. You don't mind coming back every 3-6 months to redo your Keratin Treatment

The biggest downside to Keratin Treatment is that it is only temporary. We've heard of Keratin Treatments whose effects last only 1 month and others that can last as long as 8 months, like what happened for Agent C at Chez Vous Hair Salon.

For most treatments, however, should last from 3-4 months.

How long it lasts really boils down to how well your stylist knows your hair and which Keratin Treatment they use. That's one of the reasons we love Chez Vous Hair SalonThe Bund Hair Salon and Be Salon. All 3 salons carry a huge variety of keratin solutions so there'll always be one that can best cater to your hair type.

5. You don't want to see strange kinks when your natural hair grows out

Rebonding may be permanent on existing hair that is straightened but it is unable to make sure that new hair that grows out is straight. The result is a kink at the point the rebonding was previously done. 

That means it is necessary to go back every 3-4 months to do a Rebonding touch-up for the roots. So, you are kind of stuck with Rebonding your whole life until you decide to take several years to grow your hair out.

6. Your hair is dry due to bleach

Keratin Treatment was formulated to act like a super-strong hair conditioner, replenishing your hair with much-needed hydration. Keratin Treatment may be a chemical process but some treatment utilizes organic ingredients such as aloe vera, collagen and vitamins that can help to overcome dry hair problem while promoting healthy hair.
