Normal Rebonding vs Soft Rebonding vs Treatment Rebonding in Singapore: What's the Difference?

By Auxo Hair Studio | Updated June 2026 | Hair Rebonding Singapore


If you are researching the best rebonding for your hair in Singapore, you may have come across terms like Normal Rebonding, Soft Rebonding, and Treatment Rebonding. While many salons focus on the final result, an important factor that is often overlooked is the pH level of the products used during the rebonding process.


Understanding pH levels can help you make a better decision, especially if your hair is coloured, bleached, dry, damaged, or prone to breakage.


In this guide, we'll explain the differences between the three types of rebonding, why pH level plays a significant role in your hair's health, and guides you on which rebonding suits your hair best.


Smooth Straight Hair After Rebonding


What Is Hair Rebonding?

Hair rebonding is a permanent chemical straightening treatment that restructures the internal bonds of your hair to create a straight, sleek finish. Unlike keratin treatments that coat the outside of the hair shaft, rebonding breaks and reforms the disulphide bonds within the hair cortex, permanently altering its natural texture.


The result? Smooth, straight hair that holds its shape — even in Singapore's notoriously humid weather — until new hair grows from the roots.


Rebonding has been one of the most popular hair services across Asia for decades, and Singapore remains one of the top markets for professional rebonding. But not all rebonding product are created equal. The type you choose — and the chemistry behind it — makes a significant difference to your hair's health and appearance.


What Is Normal Rebonding? (The Classic Straight Look) pH level: 10 to 11

Normal rebonding is the traditional chemical straightening process that permanently alters the hair structure. It uses strong chemicals to break down the natural bonds in curly or wavy hair and then restructures them to create straight hair.


What to expect:

  • pH level: 10 to 11 (alkaline)

  • Effect: Very straight and sleek hair

  • Duration: Results last up to 6 months with proper care

  • Best for: Healthy hair that can withstand strong chemicals

  • Benefit: Easier daily styling


Considerations:

  • Hair may appear flatter.

  • Hair may feel drier after the service.

  • Additional hair treatments are recommended to maintain moisture and softness.


The high pH level in normal rebonding opens the hair cuticles widely to allow the chemicals to penetrate deeply. This process is effective but can be harsh on hair, especially if it is already damaged or fragile.


What Is Soft Rebonding? (Natural-Looking and Frizz-Free) pH level: 10 to 11

Soft rebonding (also known as volume rebonding) became hugely popular in Singapore in recent years as more people moved away from the ultra-flat look of traditional rebonding. Instead of pin-straight results, soft rebonding gives you smooth, flowing, frizz-free hair that still looks natural.


What to expect:

  • pH level: 10 to 11 (alkaline)

  • Effect: Straight hair with a softer, more natural look

  • Duration: Lasts up to 4 months

  • Best for: Hair that is slightly damaged or sensitive but still needs straightening

  • Benefit: Easier daily styling


Considerations:

  • Still uses a relatively high pH straightening system.

  • Hair may require regular hair treatments to maintain softness and hydration.

  • Not ideal for severely damaged hair.


Soft rebonding balances the desire for straight hair with the need to protect hair health. It is ideal for people who want a less intense chemical process but still want noticeable straightening results.


What Is Treatment Rebonding? (Hair Repair & Straightening in One) pH level: 4.5 to 5.2

Treatment rebonding combines hair straightening with nourishing treatments technology to create smooth, manageable hair while helping maintain the overall condition of the hair. Unlike traditional high-pH straightening systems, Treatment Rebonding operates within a pH range that is much closer to healthy hair's natural pH level to minimize damage and includes ingredients that strengthen and hydrate hair.


  • pH level: 4.5 to 5.2 (acidic to near-neutral)

  • Effect: Smooth, Straight, and Healthier-looking hair

  • Duration: Results last up to 6 months, depending on hair care

  • Best for: Damaged, dry, or chemically treated hair needing repair and straightening

  • Benefit: Better moisture retention and easier daily styling


Because treatment rebonding uses a pH closer to the natural pH of hair and scalp, it is less harsh and helps maintain hair health. It is a good choice for those who want straight hair without compromising hair condition.

Not Sure Which Rebonding Is Suitable for Your Hair?

While the information in this guide can help you understand the differences between Normal Rebonding, Soft Rebonding, and Treatment Rebonding, the most suitable option ultimately depends on your hair's condition and history.


Factors such as:

✓ Previous rebonding

✓ Bleaching history

✓ Hair colouring

✓ Hair treatments

✓ Hair damage level

✓ Hair elasticity and strength


can all affect which rebonding service is safe and suitable for your hair.

For this reason, we do not recommend choosing a rebonding service based solely on online photos or descriptions.


Our stylists will first assess your hair in person before recommending the most suitable option. This helps ensure that you achieve the best possible results while maintaining the health of your hair.
