FAQs

What is keratin treatment?

A keratin treatment is a smoothing treatment designed to help hair appear smoother, softer and easier to manage. Traditional keratin hair treatments are typically chemical protein treatments that work on the surface of the hair to help smooth the hair cuticle. Keratin Alpha Sleek takes a different approach, acting at the Keratin Alpha level for up to 2 weeks of smooth, frizz and volume control, while helping preserve natural movement and fibre integrity.

Does keratin treatment straighten hair?

Some salon keratin services are designed to make hair look straighter, while other routines focus more on smoothness, softness and frizz control. Keratin Alpha Sleek helps hair appear smoother and more controlled with natural movement, rather than promising permanently straight hair.

How long does keratin treatment last?

Results vary depending on the service or routine used. Keratin Alpha Sleek is designed to deliver 2 weeks of smooth, frizz and volume control after 4 applications of the Shampoo + Smooth Transformer + Serum routine.

What is keratin shampoo and conditioner?

It usually refers to a haircare routine designed to support keratin smoothing, helping hair feel smoother, softer and easier to style. The Keratin Alpha Sleek range includes shampoo, Smooth Transformer, mask and serum, combining cleansing, smoothing and care steps in one professional routine.

What types of hair is the Keratin Alpha Sleek at-home keratin treatment suitable for?

An at-home keratin hair treatment can be suitable for a wide range of hair types, from straight to curly. Keratin Alpha Sleek Smooth Transformer is suitable for all hair types, including coloured hair, and forms part of a professional keratin smoothing routine designed to help improve smoothness and control frizz. It can also be used on hair that has previously undergone a straightening treatment.

Does Keratin Alpha Sleek contain keratin?

Keratin is an animal-derived ingredient that is also found naturally in human hair. Keratin Alpha Sleek does not contain keratin. Instead, the range is designed to act at Keratin Alpha level to support 2 weeks of smooth, frizz-controlled hair when used as part of the recommended routine.

What is the difference between alpha and beta keratin?

The difference between alpha and beta keratin comes down to their structure and where they are found. Alpha keratin is the primary structural protein found in human hair and helps determine each strand's shape, strength and elasticity. Beta keratin is typically found in harder biological materials such as feathers, claws and scales. Because alpha keratin forms the core structure of hair, it plays an important role in how hair looks and behaves.
