Hair Smoothing vs. Hair Straightening: What’s the Difference?

Wondering which treatment is right for your hair? At Salon ONE 9, we offer both hair smoothing and hair straightening services—but they work very differently.

Let’s break down the difference to help you choose what fits your hair goals best.

Hair Smoothing

Purpose: Tames frizz, enhances shine, and improves manageability without removing all your natural texture.

Our Hair Smoothing Services:

  • Brazilian Blowout
  • Keratin Treatment
  • BBL Free

These treatments coat the hair with smoothing ingredients (often protein or keratin) that help seal the cuticle, reduce puffiness, and add long-lasting shine. They don’t break hair bonds, so your natural wave or curl can return over time.

Best For:

Frizzy, puffy, or unruly hair
Those wanting less daily styling time
Clients who want smoother texture but not flat-straight hair

Results Last:

Around 2 to 4 months

Hair Straightening

Purpose: Permanently straightens the hair for a sleek, straight finish with zero wave or curl.

Our Hair Straightening Service:

  • Japanese Straightening

This process uses a chemical formula to break and re-form the internal hair bonds, resulting in long-lasting straight hair. It’s ideal for clients who want dramatic, pin-straight results and minimal styling maintenance.

Best For:

Coarse, curly, or textured hair
Clients looking for a long-term straightening solution

Results Last:

6+ months (until new hair grows)

Still Unsure?

No worries! Book a consultation with one of our stylists and we’ll guide you to the best option for your hair type and desired result.
