What is the Difference Between Relaxer and Keratin Treatment?

The main difference between a relaxer and a keratin treatment is how long they straighten the hair and the chemicals used in each process. Here are the key differences:

1. Duration: A keratin treatment temporarily loosens your curl pattern and fades out over time, allowing your hair texture to eventually return to its natural state. In contrast, a relaxer permanently breaks down the molecular bonds in hair, straightening it for an extended period.
2. Chemicals: Keratin treatments use a special blend of hydrolyzed keratin, which is a protein high in the amino acid "cystine". Relaxers, on the other hand, use harsher chemicals like ammonium thioglycolate and sodium hydroxide to break the hair's bonds.
3. Results: Keratin treatments last for 3 to 6 months, while relaxers last for 6 to 8 weeks, depending on hair care habits.
4. Suitability: Keratin treatments are more suitable for those with frizzy hair who want long-term straight and smooth hair. Relaxers are ideal for slightly wavy and curly hair, making the hair permanently straight.

Before opting for either treatment, it is essential to consult a professional hairstylist to evaluate if the treatments are suitable for your hair type, texture, and quality, as both treatments involve using chemicals and heat, which may damage the hair and skin.

Comparative Table: Relaxer vs Keratin Treatment

Here is a table comparing the differences between relaxer and keratin treatments:

In summary, relaxer treatments provide permanent straightening by breaking down hair's natural bonds, while keratin treatments offer a semi-permanent smoothing effect that reduces frizz and straightens hair without altering its natural curls and waves. Relaxers are more suitable for kinky or curly hair, whereas keratin treatments can be used on all hair types.
