Description

Top One is a premium salon-grade protein straightening treatment developed to deliver flawless results on all hair types — including thick, frizzy, color-treated, or resistant hair.

 

Powered by Hyalugen Technology, an innovative fusion of Hydro Collagen, Shea Butter Cetyl Ester, and a rich blend of nourishing oils (Argan, Coconut, Sunflower, and Grape Seed), it provides intense hydration, fiber repair, and long-lasting smoothness — while preserving color vibrancy and rejuvenating hair from root to tip.

 

Formaldehyde-free and enriched with advanced actives, Top One enhances shine, restores softness, and protects hair integrity — offering exceptional straightening performance with professional precision and salon-grade care.

How to use it

Wash hair with Top One Shampoo and dry completely. Divide into six equal parts and apply Top One Protein evenly from roots to ends using steady, long brushstrokes. Leave on for 30–60 minutes, rinse around 60% with water, blow-dry, and flat iron each strand 10–20 times at 230°C. For best results, finish with Top One Nourishing Mask for 5 minutes, rinse, apply Top One Conditioner, and complete the treatment with Top One Serum before blow-drying.

 

Adjust these steps based on hair analysis and desired results. Perform a strand test before use.

Expected results

Flawless straightening, radiant shine, and long-lasting smoothness — all while preserving the hair’s health and color vibrancy. Expect intense nourishment, deep hydration, and frizz elimination with a rejuvenated, silky finish in just one session. Clients notice stronger, healthier-looking hair, return sooner, and trust you for premium transformations.

Top One FAQs

Does it straighten without damaging the hair?

Absolutely. It smooths the hair using amino acids and proteins, without breaking bonds or causing long-term damage. No formaldehyde, no aggressive chemicals.

Is it safe for pregnant clients or children?

Yes, it's formaldehyde-free and non-toxic, making it safe. Just like any professional hair care service, we recommend consultation before use.

Will it change the natural structure of the hair?

No. It doesn’t break internal bonds. It temporarily realigns the fiber while treating and smoothing the outside, with no permanent alteration.

How long does it last? Can I reapply anytime?

It lasts 3 to 6 months, and yes, you can reapply anytime, even just on regrowth. No buildup. No damage. Just smoother, healthier hair.

Can I adjust the result—smooth or straight or curl definition?

Yes. The final look depends on temperature and technique. Go for ultra-straight, natural smoothness, or defined frizz-free curls.

Does it penetrate or just coat the hair?

It penetrates the cortex, treating the fiber from the inside. Heat seals the actives in, so results last longer and hair stays stronger.
