Each option below is written in client-friendly language so you can compare the result, the feel and the maintenance expectation.
Permanent Straightening
Also known as Japanese Straightening / Rebonding / Thermal Reconditioning
Permanent straightening is the traditional straightening service for clients who want a strong, sleek and fully straight result. It permanently changes the structure of the treated hair, so it is best suited to clients who want curls or waves fully straightened rather than softened.
- Best for clients who want an intentionally sleek, straight finish.
- Changes the treated hair structure permanently.
- Not recommended for bleached hair.
Nanoplasty
Nanoplasty is a newer straightening technology powered by amino acids and organic acids rather than formaldehyde or other aggressive agents. It is positioned as an advanced long-lasting straightening option for clients who want smoother, shinier, softer and easier-to-manage hair with a more natural-looking finish than older straightening methods.
- Often lasts around 4–8 months.
- Designed for smoother, shinier, softer and easier-to-manage hair.
- Can be suitable for many bleached or damaged hair types after professional consultation.
- Can help add some softness and gloss to damaged hair.
Smooth Filler
Smooth Filler is a demi-permanent smoothing treatment, similar to what many clients know as Hair Botox. It reduces frizz and makes hair smoother, softer, shinier and easier to manage while keeping natural curls or waves.
- Lasts up to 3 months.
- Keeps natural texture and does not permanently straighten curls.
- Ideal for a Hair Botox-like smoothing result.
- Good for clients who want less frizz without losing movement.
Olaplex Treatment
Olaplex is a bond repair treatment for damaged, bleached, colour-treated or fragile hair. It focuses on strengthening weak hair and helping reduce breakage rather than changing your hair shape.
- Helps repair damaged bonds inside the hair.
- Ideal for bleached and chemically processed hair.
- Supports stronger-feeling hair and less breakage.
Conditioning Treatment
A conditioning treatment is a short-term nourishing service for moisture, softness and regular maintenance. It is ideal when your hair feels dry, dull or in need of a quick refresh.
- Improves softness and helps dryness.
- Adds basic smoothness and shine.
- Best for short-term maintenance rather than structural change.
