Why is hair very damaged after bleaching?
Bleached hair undergoes an oxidation chemical reaction that permanently changes its integrity and reduces its resistance.
With the penetration of aggressive agents (ammonia, oxygenated water) to the heart of the hair fibers, all hair’s natural properties are impacted:
- The mechanical properties are altered: the hair becomes fragile and easy to break.
- The surface properties are changed: hair becomes drier, more coarse, more difficult to detangle, and its porosity increases.
In short: after bleaching, hair needs some extra love and attention, it’s been through a lot of changes!
Why does bleached hair become sensitive?
When bleached, hair becomes sensitized. It can even become thinner, and the texture altered by bleaching.
Bleaching “ strips hair bare ” and weakens it against different daily aggressions such as blow drying, straightening, styling with curling iron, sun exposure or even the wrong type of hair product,
Already weakened by bleaching, hair continues to worsen: the integrity of the hydrolipidic film is damaged, the hair fiber isn’t protected against dehydration and dryness, which continues to make hair more fragile.
As a result, bleached hair needs even more care than natural hair, to repair damage caused by bleaching. To help hair restore itself, hair needs external moisturizing, nourishing and protective active ingredients through natural, rich and targeted hair care. To combat this, hair care and treatments should be used to help restore and maintain hair’s strength and shine.
Why does colored blonde hair become dull?
Immediately after bleaching, balayage or highlights, hair is protected. Its very smooth scales maximize the light-reflecting power, giving hair a lustrous sheen.
But over time, this effect disappears and hair’s scales open up. Bleached and dyed blonde hair tends to age poorly: it’s one of the most difficult colors to maintain, given it tends to oxidize more quickly in the air, meaning it’s duller or has a green tinge. Blonde hair also requires more protection against UV rays, salt and chlorine, which can alter its color.
When hair cuticle scales lift due to everyday aggressors, hair’s shine disappears and the blonde becomes duller.
To maintain bright blonde and beautiful hair, regular bleaching to avoid the ‘” roots ' effect and frequent use of specific care is needed.
