What It Is

The Lengths Renewing Mask is the perfect treatment for long hair suffering from thinned ends.

What It Does

• Reduces the appearance of split ends by 31%.*

• Filler A-100 has a high concentration of patented filling molecule to thicken and resurface the hair fiber.

• The Amino Acid strengthens and renews lengths.

 

*When used with Pro Longer Shampoo + Pro Longer Masque versus unwashed hair.

Shampoo with Serie Expert Pro Longer Shampoo. Apply Masque on towel-dried lengths. Leave in 3 to 5 minutes. Rinse out. Treat with Renewing Cream for Lengths & Ends

 

PRO TIP: Once a week, have your clients replace their Lengths Renewing Masque with the Ends Filler Concentrate to durably fill and thicken ends.

Rated 1 out of 5 by from Too much fragrance I hadn’t bought products from Loreal in a while, recently bought 2, an oil and this hair mask for myself and the amount of fragrance in their products should be illegal, it is extremely overwhelming… headache and makes me feel like im eating it, really gross and so bad for your health btw! Never experienced this with any other brand, I cannot use these products after only using the mask once and the oil twice. Disappointing to say the least…

Rated 5 out of 5 by from LOVE THIS LINE I’ve been using this religiously on multiple clients who come in weekly. They fit the bill for the product. Let me tell you, we instantly saw results! Thicker, fuller, stronger hair. Absolutely recommend this to anyone with fine haired client who want to have that fullness and thickness, but also don’t want a haircut every 6-8 weeks.
