Rebonding vs Keratin Hair Straightening Treatment

Looking for a hair treatment in Singapore that helps control or remove frizz, but not sure which one to choose? You’re not alone. With so many options available, it can be confusing to know what actually works for your hair. At our hair salon in Singapore, two of the most common choices clients go for are keratin treatments and rebonding.

A keratin treatment is a professional hair-smoothing service that restores keratin protein back into the hair. It helps repair damage, reduce frizz, and improve manageability, leaving the hair smoother, shinier, and more polished without making it completely straight. In contrast, rebonding is a chemical process that permanently straightens the hair by changing its internal structure. It delivers a sleek, pin-straight finish with very high frizz control, but the results grow out over time as new hair comes in.

At our hair salon in Singapore, we offer both treatments. The right choice depends on your hair type and the result you want. We also provide a complimentary consultation before every appointment so our hairstylists can assess your hair and recommend the best treatment for you.

1. What is hair rebonding?

Hair rebonding is a chemical process that permanently straightens the hair by changing its internal structure. It works by breaking down the natural bonds in your hair and restructuring them into a straight form.

After rebonding, the hair becomes pin-straight, flat, and sleek. It also offers very high frizz control, making it a popular choice for those with very frizzy, thick, or naturally curly or wavy hair who want a consistently straight look.

A keratin treatment is a professional hair treatment in Singapore that smooths the hair by restoring keratin protein back into it. It helps repair damage, reduce frizz, and improve manageability, leaving the hair smoother, shinier, and naturally straighter. Since keratin is a protein that gives hair its strength and structure, this treatment is especially helpful if your hair has become dry or frizzy from heat styling, chemical services, or environmental factors.

Keratin treatments are suitable for those with frizzy, dry, or naturally wavy to curly hair. They also work well on color-treated hair, helping to enhance and maintain the color for longer. After the treatment, you can expect smoother, softer hair with reduced frizz, improved texture, and noticeable shine.

3. Rebonding vs keratin: Key differences

The main difference comes down to the result you want. If you prefer a super straight, sleek look with almost no frizz, rebonding is the better option. 


If you want smoother, more manageable hair that still looks natural and keeps some movement, a keratin treatment is more suitable. 


Both can help straighten your hair, but the right technique depends on your hair’s current condition and your desired result.


Rebonding gives a super straight, sleek look, but we can also do a soft rebonding for a more natural-looking result.


Rebonding uses chemicals to break and restructure hair bonds, while Keratin does not permanently change your hair structure.


Keratin is good for frizz control, while rebonding is good for straightening hair. Keratin keeps volume and movement.


Keratin-treated hair cannot be permed or bleached within 6 months. Services are advised after 6 months, when the full keratin coating wears off.


Rebonding lasts for 3-6 months, while keratin lasts for 1–3 months. A proper homecare routine is very important to prolong the effects.


At our hair salon in Singapore, rebonding starts at $140 with Junior Stylists, while keratin treatments start at $370 with Senior Stylists.

4. Maintenance and aftercare

Keratin Hair Treatment

  • The first 72 hours: After your keratin treatment at our hair salon in Singapore, the first few days matter. Avoid washing your hair for at least 72 hours so the treatment can fully set.

  • Washing do’s and don’ts: When you’re ready to wash your hair, timing and product choice are key. Wait at least three days before your first wash. Use shampoo and conditioner designed for keratin-treated hair, as harsh formulas can strip away moisture and bring back frizz.

  • Hairstyling tips: Always use a heat protectant before using styling tools to reduce damage. Heat protectant hair care products are available at the Kimage e-Shop.

  • Product recommendations: Do not use deep cleansing shampoos as they can strip the keratin coating.

  • Lifestyle considerations: Daily habits can affect how long your keratin treatment lasts. If you swim often, protect your hair from chlorine and saltwater, as both can reduce the treatment’s effect.

Rebonding

  • The first 72 hours: Just like keratin hair treatment, keep your hair straight and loose, and avoid tying or clipping it.

  • Washing do’s and don’ts: Once the waiting period is over, use gentle, moisturizing shampoos and conditioners to keep your hair hydrated.

  • Hairstyling tips: Minimise heat styling where possible, as rebonded hair is more prone to dryness. If you do use heat tools, always apply a heat protectant.

  • Lifestyle considerations: Regular touch-ups may be needed to maintain a consistent look. Keeping your hair well-conditioned and trimmed will also help manage the difference between treated and new hair growth.
