How to treat damaged hair

Do you suffer from damaged hair? Many people misdiagnose their hair as simply dry, but perhaps there’s more to it than that. Here’s how to identify your hair’s needs, and whether you need hair treatment for damaged hair.

Do I have damaged hair?

Here’s the difference between dry and damaged hair:

Dry: lacking natural oils that smooth and lubricate the hair. Dryness can be caused by heat styling, changes in temperatures or it can be dry simply because your scalp produces less oil.

Damaged: lacking proteins required to keep hair strong. Protein bonds have been broken, often due to intense hair treatments and styling.

How to test for damaged hair

The hair strand test: take a strand of hair and hold it out at both ends. Slightly pull the hair so that it stretches. Healthy hair should stretch up to one-third of its length. If it snaps quickly, this is a sign of protein damage. If it stretches but returns misshapen, or remains stretched even when no longer pulled, this points to dryness.

Another simple test is to hold an inch-wide section of hair between your fingers and stroke gently down to the tips. If you feel unevenness, and some hairs snap, you may have protein damaged hair.

Still not sure whether your hair is dry, damaged or perfectly healthy? Simple: just book a visit to your local hairdresser. If in doubt, always trust the professionals!

What can cause hair damage?

The most common is the at-home hair straightening tool, not only due to its popularity but because many people do not use the right heat protective treatment before styling. Hair curlers are also major culprits, as is excessive colouring (especially repeated lightening) and permanent hair treatments like in-salon straightening and curling.

Damaged hair treatment: Where to start

Truly damaged hair needs to visit the hair hospital. Luckily, it’s a far more enjoyable experience than a visit to the doctor!

The Pro Fiber haircare treatment programme from L’Oréal Professionnel starts with an expert in-depth consultation at the salon.

You’ll then be treated to a tailored shampoo from the Pro Fiber range, depending on your hair’s needs.

After cleansing and enjoying a relaxing head massage (which also stimulates healthy hair growth), your hairdresser will continue with the treatment by adding the Masque to damaged lengths and ends for 5 minutes.

The masque includes technology: Aptyl 100 providing both surface-level and deeper repair for damaged hair. Once 5 minutes is up your stylist will rinse thoroughly.

Once dry, try the hair fibre tests we mentioned previously and you will really feel the difference!

Home hair treatment for damaged hair

Because no-one expects you to visit the salon every time you need to wash your hair, the Pro Fiber range also includes home haircare tailored to you. 

Extend and recharge the Pro Fiber in-salon treatment with Aptyl 100 by using the Pro Fiber at home. Advanced, professional repairing technology restores damaged hair by ridding the sensitised hair fibre of impurities that weaken it, whilst reviving the unique APTYL 100 in-salon protocol care effect. The result? Long lasting intensive care for damaged hair.

Different levels of damage: personalised haircare

Depending on your level of damage, your hairdresser will prescribe the perfect routine for you:

Re-create: for fine to medium, damaged hair . Many women are born with naturally thin hair that is therefore much more vulnerable to damage.

Reconstruct: for thick, damaged hair often caused by over-using heated styling tools and excessive colouring.

Avoid damaged hair

If your hair isn’t yet suffering from signs of damage, be cautious when using styling tools, and always see a professional when it comes to colouring and other treatments such as permanent straightening or curling.
