Profile: Brittle/Damaged Hair

Definition: Hair in which the hair fibres have lost their strength and elasticity, meaning they break at the slightest aggression. The hair appears dull, dry, split, rough, straw-like, difficult to style, and with split ends. This phenomenon is explained by the disappearance of the hydrolipidic film, increasing the vulnerability and exposure of the hair to external aggressions, by a disassociation of the scales exposing the interior of the hair and causing excessive evaporation of the water naturally present in the hair, and by the damage suffered by the keratin chains.

Internal and external causes: Stress, prolonged exposure to the sun, deficiency in vitamins and minerals, repeated straightening and colouring, intensive use of hairdryers/straighteners, excessive and incorrect brushing especially on wet hair, overly tight hairstyles, lack of sleep, overly aggressive towel drying, smoking, use of unsuitable hair accessories.

How to reduce or eliminate: Smooth the scales and restore the original protection of sensitised hair fibres with the application, strand by strand, of a re-lipidating and repairing mask (squalane, ceramides, keratin, oils, butters...); trim the ends when they are too damaged.

Preventative steps to take: Do not skip the conditioner; apply oil to the lengths before washing your hair to protect it; limit the use of heat sources (blow-drying, straightening, curling...); limit chemical treatments (relaxers, colouring...); avoid brushing your hair too aggressively; dry your hair gently without rubbing; avoid touching/playing with your hair; equip yourself with a silk pillowcase to minimise friction during the night or plait your hair; spray your hair with a heat-protective mist before using a heated device; protect your hair from the sun; avoid sleeping with wet hair; opt for a hair diffuser for an even distribution of heat and thus protect the hair fibre from the blow-dryer's blast.
