Keratin and amino acid hair treatments can both reduce frizz and improve manageability, but they work differently and can create different results. Keratin treatments mainly smooth and soften the hair, while amino acid systems are designed to restructure the hair more deeply and may provide stronger straightening results depending on the formula and hair type.
What Is a Keratin Hair Treatment?
Keratin treatments are smoothing treatments designed to reduce frizz and make hair easier to manage. They work by coating the hair with keratin and sealing it into the hair using heat from a blow dryer and flat iron.
These treatments usually help improve shine and smoothness but typically do not permanently straighten very curly or resistant hair.
What Is an Amino Acid Hair Straightening Treatment?
Amino acid hair straightening treatments work differently. These systems use amino acids and heat activation to help restructure the hair and create straighter, smoother, and more manageable hair.
Because of this process, amino acid systems can provide stronger straightening results while still improving the overall appearance and manageability of the hair.
Example of an Amino Acid Straightening System
One example of a professional amino acid hair straightening system is Bio Sleek by Nano Lamination. This treatment is designed for professional salon use and helps permanently straighten curly or frizzy hair while improving shine, smoothness, and manageability.
Bio Sleek uses a washable system that allows hairstylists to check the results the same day and ensure predictable, consistent straightening outcomes.
Choosing the Right Treatment
The choice between keratin and amino acid straightening treatments depends on the client’s hair type and the desired results. Clients who want smoother hair with reduced frizz may choose keratin smoothing treatments, while clients who want stronger straightening results may benefit from amino acid straightening systems.
Consulting with a professional hairstylist is the best way to determine which treatment is most suitable for each hair type.
