Anyone with frizz-prone hair who wants a deeper smoothing treatment than a daily conditioner: poofy curls, fluffy waves, wispy or staticky straight hair. Matrix recommends it for all hair types.

It is especially useful in humid summers and dry, heated winters, and for hair that tangles or feels rough. Salon professional formula, easy to use at home.

Smoothie Supreme is the concentrated step in the Mega Sleek line. Where the conditioner keeps hair smooth day to day, the mask gives the fibre a bigger dose of moisture and conditioning so it is less likely to swell in humidity or fly away in dry air. Used once or twice a week it keeps frizz under control between washes, and it detangles well enough to make styling faster.

• Shampoo with Mega Sleek Smoothing Shampoo and gently squeeze out excess water.
• Apply from mid-lengths to ends.
• Leave on for 3-5 minutes, then rinse.
• Use 1-2 times per week in place of the conditioner. Style with Mega Sleek 96H Topcoat.

Pros:

• Short 3-5 minute treatment that fits a normal wash day
• Visibly smoother, more manageable hair; strong detangling
• Designed to keep working in humid or dry air
• Large 500 ml jar

Cons:

• A rich formula; fine hair should use a small amount and keep it off the roots
• Contains silicone (amodimethicone) and fragrance
• Best results come with the rest of the Mega Sleek routine
