Keratin Treatment vs. Other Hair-Smoothing Treatments

When you decide between a keratin treatment and hair smoothing treatments, it’s important to understand the differences in terms of longevity, results, hair health, and purpose. 

What is a keratin treatment?

Keratin is best for reducing frizz, softening curls, and making hair more manageable. Keratin protein is infused into the hair and sealed using heat, creating a temporary protective coating that smoothes the cuticle of the hair. The purpose of keratin is to smooth hair, reduce frizz, and add shine while retaining natural volume. The key benefit of keratin is to reduce daily styling time by making hair easier to straighten and style. Its longevity is around 3 to 4 months with proper aftercare. 

Brazilian Blowout: Brazilian blowout is a type of keratin treatment that smooths frizz without completely removing waves and curls from hair. It is best for those people who want frizz-free hair without losing volume or curls. It is a very quick process with no downtime; the hair can be immediately washed after treatment. 

Japanese Hair Straightening: Japanese hair straightening permanently straightens hair by breaking and restructuring bonds within the hair shaft. It is best for those people who have very curly hair and who want straight hair. Japanese hair straightening is a chemical solution that breaks the hair’s natural bonds, and heat is applied to reshape it straight. 

Relaxers (Chemical Hair Straightening): Relaxer straightens curly or kinky hair by permanently altering its structure. Chemical relaxers break down bonds in curly or wavy hair, leaving it straight. It is best for coarse, very curly, or textured hair. It can weaken the hair, leading to breakage if not maintained properly. 

Hair Botox: Hair Botox deeply smooths, conditions, and restores damaged hair without altering its natural curl or wave. Hair botox is a blend of vitamins, collagen repairs, and proteins that reduce frizz and improve shine. It is best for damaged, frizzy, or over-processed hair that needs hydration and smoothness. It is non-chemical and suitable for most hair types.

Schedule Touch-Ups: Depending on how quickly your hair grows and how well you care for your treatment, touch-ups every 4-6 months can help maintain consistent results.
