Straightening has gone badly wrong: what can you do?
Are there any side effects that have affected your new straightening? Don't panic, we're here to help.
Whether progressive or permanent, straightening is certainly one of the most sought-after treatments in hair salons. Before embarking on using chemicals, it's important to choose a trusted professional (straightening at home or by an amateur is not recommended at all) and to have the right products available. For example, in France the concentration of formaldehyde in products intended for straightenig must be less than 0.2 % as the substance is harmful at higher doses. Check if your hairdresser respects this standard and do not hesitate to ask him/her to perform a sensitivity test before carrying out the straightening.
Analysing the condition of your hair is also an essential step. "Well-maintained hair will resist damage more easily and handle products better" says Gui Cassolari, official hairdresser of Natura Brasil. He also reminds us of the importance of playing fair with the professional by providing information about any products and treatments carried out in the past. "The chemicals used in previous dyeing and straightening have a big influence on what happens next,", he says.
But even with all this advice, things can go wrong. "If straightening has damaged your hair or if it hasn't worked, the first thing to do is to get a diagnosis of the condition of the hair and then treat it", explains the expert. We have listed the most frequent problems when straightening goes wrong with solutions to fix them.
1. Brittle hair
After repeated straightening, hair is often weaker and more difficult to untangle. If the hair starts to break, you should think about using a repairing treatment, based on keratin, amino acids and vitamins, and intense hydration. The initial stage is usually carried out in the salon, with the maintenance is carried out at home, as part of a process that can last over a month. If the hair is very damaged, the only solution will be to give it a good cut.
2. Scalp reactions
"This is more common with progressive straightening than with permanent straightening", says Gui Cassolari. The sensitivity test performed by the hairdresser can detect some intolerance to the product. But if the scalp shows irritation or flaking despite the absence of any skin reaction, it is advisable to consult a dermatologist.
3. Hair is "stuck" to the top of the head.
This can sometimes happen in the first two weeks or the first six washes. "If this happens, blow dry your hair upside down until it "unsticks" and you get volume at the roots", explains Gui Cassolari.
4. Straightening didn't work
Talk to your hairdresser about the ideal time interval before trying straightening again. "Straightening it twice in a row can lead to brittle hair or even hair loss", says the expert. He also points out that the problem is common in virgin hair because it has closed pores and is less receptive to chemicals.
5. The hair has changed colour
Certain types of progressive straightening can change the tone of coloured hair, mainly on blonde women and those with highlights. "But there are specific products on the market that prevent this effect. If it happens, you can neutralize the change with a tone on tone colour", concludes the expert.
