Straightening – Japanese Precision Smoothing

Mirror-Shine Straight Hair

Our signature Japanese straightening goes far beyond traditional treatments. Years of testing, advanced formulations, and continuous technique development create a uniquely soft, glossy finish that feels like healthy, natural hair.

 

Why choose our straightening service?

  • Dream of supple, naturally straight hair
  • Unsatisfied with previous straightening treatments
  • Told elsewhere that your hair was too damaged for straightening
  • Want to avoid any further breakage
  • Find daily flat-ironing a hassle
  • Love running your fingers through silky-smooth hair all day
  • Longing for breathtakingly sleek hair

What Makes Our Method Different

Straightening is a highly advanced craft that blends science and art. We start with an in-depth consultation, analysing your hair’s texture, history, and strength. Using a formula tailored to you, we adjust product for roots, mids, and ends—maximising hair stamina while achieving lasting shine.

Ideal for difficult-to-manage hair

If your hair is badly damaged, colour-treated, or you simply want a smoother result than ever before, try our PIAR Signature Straightening & Special Treatment.

How we repair and protect

Hair’s moisture and lipid balance changes daily. We infuse CMC, collagen, keratin, and specialised proteins exactly where needed, then craft a bespoke chemical blend using the latest professional products and our experience.
