FAQs
What does an alpha keratin hair mask do?
An alpha keratin hair mask helps smooth the hair fibre while improving softness and manageability. The Keratin Alpha Sleek Mask combines Keratin-Alpha Shaper technology with amino acid chains to help control frizz and leave hair feeling smoother, softer and easier to style.
Does the Keratin Alpha Sleek hair mask straighten hair?
No. The Keratin Alpha Sleek Professional Hair Mask does not permanently straighten hair. Instead, it helps smooth the hair fibre, reduce visible frizz and improve manageability for a sleeker finish. This professional alpha keratin smoothing mask is designed to support smoother-looking hair while maintaining natural movement and body.
Can I use the Keratin Sleek Alpha Keratin Hair mask for curly hair?
Yes. Curly hair can benefit from additional nourishment and frizz control, particularly in humid conditions. The Keratin Alpha Sleek Mask helps smooth the hair fibre while maintaining natural movement and curl pattern. This formula helps leave curls softer, smoother and easier to style without making hair feel heavy.
Can I leave the Keratin Alpha Sleek hair mask on overnight?
No. The Keratin Alpha Sleek Mask is designed to work within a five-minute treatment time before rinsing. Leaving a hair mask on overnight is not necessary to achieve the intended benefits. For best results, apply evenly through lengths and ends after shampooing, leave on for five minutes, then rinse thoroughly as directed.
How often should I use the Keratin Alpha Sleek hair mask, and can I use it every day?
The Keratin Alpha Sleek Professional Hair Mask can be used on every other wash day to help maintain softness, nourishment and smoothness. Rather than daily use, it is designed to complement the Keratin Alpha Sleek routine, with Smooth Transformer recommended weekly and the mask every other wash.
Does the Keratin Alpha Sleek Mask contain keratin?
No, it does not contain actual keratin proteins. Instead of adding animal-derived keratin to the formula, the mask contains amino acid chains (like glycine) and specialised "Keratin-Alpha Shapers" to help improve smoothness, softness and manageability.
Is the Keratin Alpha Sleek Mask suitable for frizzy hair?
Yes. Frizz-prone hair often benefits from additional conditioning and smoothing care. The Keratin Alpha Sleek Professional Hair Mask helps nourish the hair fibre, improve manageability and reduce visible frizz, leaving hair softer and smoother with natural movement.
