L'Oréal Professionnel Pro Longer Lengths Renewing Mask

L'Oréal Professionnel Pro Longer Lengths Renewing Mask is an intensive professional hair mask created for long hair with thin, weakened ends.

Powered by patented FILLER-A100 technology and Amino Acid, the formula works on areas where the hair needs extra support, helping thicken the appearance of long hair while leaving lengths visibly stronger, healthier and shinier.

It is the richer treatment step within the Pro Longer routine, ideal when long hair needs more intensive conditioning than a regular conditioner.

Nourish → Strengthen Lengths → Thicken the Appearance of Ends → Reduce Split Ends → Enhance Shine

What Is It?

Pro Longer Lengths Renewing Mask is an intensive strengthening and conditioning mask for long hair suffering from thinning ends.

As hair grows longer, repeated brushing, heat styling, colouring and environmental exposure can leave the oldest sections of the hair more vulnerable to damage, breakage and split ends.

The Pro Longer Mask specifically focuses on maintaining the quality of the lengths and ends, helping long hair look fuller and healthier rather than progressively thinner towards the tips.

Its main positioning is:

Long Hair + Thin Ends + Split Ends + Breakage + Strengthening + Fuller-Looking Lengths
