How to use it by Cut by Fred

@cutbyfred

For the vast majority of women, damaged hair is a daily challenge. Pro Fiber offers a tailor-made in-salon solution for all levels of damage.
  1. 1

    INITIATED IN SALON

    In salon

    The Pro Fiber programme starts exclusively in-salon with your hairdresser’s consultation. Your hairdresser will analyse the level of damage in your hair and then prescribe your customised Pro Fiber solution adapted to the level of sensitisation of your hair fibre.

  2. 2

    LONG-LASTING REGENERATION

    In salon

    After the diagnosis, the hairdresser applies the Pro Fiber treatment suitable to your level of hair damage. RECTIFY - to resurface hair with a damaged cuticle, RESTORE- to repair hair with a damaged cuticle and cortex, or RECONSTRUCT - to restructure hair with a very damaged cortex.

  3. 3

    REACTIVATED AT HOME***

    At home

    Your prescribed at-home Pro Fiber routine prolongs the effect of your in-salon treatment by reactivating the damage-repair technology used in salon.

15 years of Research

It’s the best formula we've ever achieved in the field of damaged hair.

After 15 years of intense research, L’Oréal’s Research laboratories have developed our most sophisticated haircare technology to date: the APTYL 100 molecular complex. By combining Aminosilane with a unique cationic polymer, L’Oréal Research has, for the first time, paved the way to a new generation of long-lasting haircare. L’Oréal Research has performed numerous tests to demonstrate both the efficacy and durability of APTYL 100.

3 levels of damaged hair 3 complete ranges

Inspired by L’Oréal Research’s understanding of damaged hair, L’Oréal Professionnel has identified three levels of damaged hair : level 1, only the cuticle is affected; Level 2, the cuticle and cortex are both affected; Level 3, the cuticle and cortex are very damaged.

Thanks to a thorough understanding of hair damage L’Oréal Professionnel has designed 3 specific Pro Fiber ranges adapted for each level of hair damage : RECTIFY, RESTORE, RECONSTRUCT. These ranges offer a targeted response to each level of damage for exceptional results.

After the Pro Fiber treatment in salon, I noticed that my hair felt thicker and stronger, as if I had denser hair.

Unlike other treatments, Pro Fiber doesn’t make the hair feel heavy and flat, instead it feels light and smooth.

Even after using a lot of heat styling tools (and I mean a lot) Pro Fiber left my hair feeling smooth and thick without weighing it down.

I often visit the salon for hair treatments but have never noticed a change. However, since using Pro Fiber my hair now feels noticeably stronger and thicker.
