The Difference Between Hair Smoothening and Hair Rebonding: A Detailed Comparison

Hair smoothening and hair rebonding are two popular hair treatments that can help to transform curly, frizzy hair into sleek and manageable tresses. Although they might seem similar, there are significant differences between these two hair treatments in terms of the techniques used, results achieved, and maintenance requirements.


Hair smoothening is a chemical treatment that involves using mild relaxers or keratin-based products to tame frizzy or curly hair. The stylist applies the smoothening product to the hair, which is left on for a specified amount of time. After washing off the product, the hair is blow-dried and straightened with a flat iron to seal the product and achieve a smooth, frizz-free look. The entire process can take anywhere between 2 to 4 hours, depending on the length and thickness of the hair.

Hair rebonding, also known as hair straightening or hair relaxing, is a more intense chemical treatment that involves breaking down the natural bonds in the hair and creating new bonds in a straighter pattern. The process involves applying a chemical relaxer to the hair, which breaks down the bonds that give the hair its natural shape. The hair is then flat-ironed to create the desired straightness. Once the hair is straightened, a neutralizing agent is applied to lock in the new shape. The entire process can take up to 6 hours or more, depending on the length and thickness of the hair.


The results of hair smoothening are less dramatic than hair rebonding, but it helps to reduce frizz and enhance shine, making the hair look more manageable and healthy. The effect of smoothening usually lasts between 2 to 4 months, depending on the hair type, care, and maintenance. The hair retains some natural movement and texture, and it can be styled in different ways.

Hair rebonding creates a pin-straight look that can last for up to six months or more. The hair is completely straightened and loses most of its natural texture and movement. The hair becomes more manageable and easier to style, but it requires a lot of care and maintenance to keep it healthy and prevent breakage.


Hair smoothening requires minimal maintenance after the treatment. It's essential to avoid washing the hair for the first 2-3 days after the treatment, to allow the product to settle in. It's also crucial to use sulfate-free shampoos and conditioners that are gentle on the hair. Regular oiling, deep conditioning, and trimming the ends can help to maintain the health of the hair.

Hair rebonding requires more care and maintenance than hair smoothening. It's crucial to avoid washing the hair for at least three days after the treatment to allow the hair to set. It's also essential to use a sulfate-free shampoo and conditioner to avoid stripping the hair of its natural oils. Regular oiling, deep conditioning, and trimming the ends are also essential to keep the hair healthy and prevent breakage.

In summary, hair smoothening is a milder treatment that can help to reduce frizz and enhance shine, while hair rebonding is a more intense process that can create pin-straight hair. The choice between the two treatments depends on your hair type, desired look, and lifestyle. It's best to consult with a professional stylist to determine which option is best for you.
