Straightened hair FAQ
If you want smooth, glossy hair, a keratin treatment is a good solution. It’s one of the best treatments for making hair straight, silky and frizz-free. Here’s how to maintain keratin-straightened hair.
A keratin treatment is a chemical salon procedure that makes hair smoother, glossier and straighter. A solution containing keratin – a protein found in hair, skin and nails – and other ingredients is brushed onto your hair. Adding keratin helps strengthen and smooth your hair.
The hair is washed and a stylist brushes the keratin solution onto towel-dried hair. It’s left for 15 to 30 minutes to soak in. Then the hair is blow-dried and ironed straight in tiny sections to seal in the product.
Some stylists prefer to blow-dry the hair first and apply the treatment to dry hair. Either way, the treatment can take up to four hours, depending on the product, the stylist, your hair length and hair type.
A keratin treatment leaves hair intensely shiny, straight and frizz-free. Your hair will be more manageable and easy to style. It will take much less time to blow-dry.
With the right aftercare, most treatments last between three and six months.
A keratin treatment is sometimes called a Brazilian blowout, a Brazilian keratin treatment or BKT. The name depends on the brand or keratin treatment product used in the salon.
Everyone wants to know how to keep hair straight after a keratin treatment. There are certain steps you should follow strictly.
Stay away from water for four days. Don’t wash your hair for at least 72 hours and ideally try to leave it for four days. Water allows keratin, moisture and other nutrients to leak out. Give your keratin treatment time to settle and be thoroughly absorbed into your hair.
Avoid damp and humid environments. This includes swimming pools, steam rooms, saunas and gyms. Remember, every time your hair absorbs water it swells. This allows the keratin to leak and leads to frizziness and kinks in the hair.
Wear your hair loose. Don’t tie your hair in a ponytail, wear a headband or put hairclips, pins or slides in your hair. Definitely don’t wear braids. Don’t push your glasses up onto your head or put your hair behind your ears. These will all cause kinks in your hair.
Don’t over-exert yourself and sweat. Avoid strenuous exercise that causes you to perspire. Perspiration is water and it will cause your hair to swell. Ideally, avoid any strenuous activity for a few days. When you do start exercising, apply a leave-in conditioner before working out.
Avoid any other hair chemical treatments for three weeks. Chemical treatments open your hair cuticles. This will allow the keratin treatment to “bleed” prematurely.
You can use any professional shampoo after a treatment, but it will not help extend the life and structure of the treatment.
For lasting results after a keratin treatment, always use a gentle, restorative aftercare shampoo that injects more keratin into treated hair.
You also need to know how to wash hair after a keratin treatment. Experts recommend shampooing with tepid water and finishing with a cool rinse.
As well as aftercare shampoo, you must follow-up with a calming and moisturising anti-frizz conditioner. It works to immediately seal the cuticles after shampooing to give a shinier and smoother look while reducing frizz further. Active ingredients extend the lifespan of your keratin treatment.
Occasionally, substitute your conditioner for an intensely hydrating mask. This will strengthen and restructure your hair to create smoothness and natural shine. How long you leave the mask on will depend how naturally frizzy or curly your hair is.
There are a variety of aftercare products and treatments you can use on your keratin-treated hair, but choose carefully and use them sparingly.
Leave-in conditioners containing keratin, collagen or polypeptides will strengthen your hair.
Shine serum creates a protective barrier between the hair shaft and the environment to provide humidity protection and instantly eliminate frizz and fly-away strands.
Oils provide maximum nourishment to strengthen brittle hair and protect against damage caused by UV rays and hot styling tools.
Now you know how to maintain keratin-treated hair. Unfortunately, some people experience hair breakage after a keratin treatment.
A keratin treatment makes your hair feel silky, shiny and frizz-free but some of the chemicals used are harsh. In the long run, they can cause damage. Some people experience hair and skin problems after getting keratin (or other chemical straightening) treatments. Problems can include:
- hair breakage
- brittle hair
- hair loss
- hair patchiness
- skin rashes and blisters.
Try to choose a keratin treatment with a low percentage of (or no) formaldehyde. Formaldehyde-free keratin treatments are increasingly available in salons.
In order to prevent brittle hair and breakage, it’s essential to know how to care for keratin-treated hair and how to keep keratin-treated hair healthy.
Start by using hair products recommended for maintaining keratin-treated hair.
You’re in for a quick chemistry lesson here. Formaldehyde is a gas. Technically, keratin treatments don’t contain formaldehyde. They do contain methylene glycol, formalin, methanal or methanediol, which, when heated or mixed with water, release formaldehyde gas.
It’s the formaldehyde (not the keratin) that straightens your hair. To understand what happens, you need to think of straight hair as a ladder and wavy or curly hair as a spiral staircase. Imagine the steps are bonds.
To make curly hair straight, the bonds – the steps – are broken and the shafts straightened to create the straight hair (ladder) from wavy hair (the spiral staircase). It’s the formaldehyde that does this and then locks your hair into a straight position.
It’s important to know that formaldehyde is classified as a human carcinogen (a cancerous product) by the International Agency for Research on Cancer. As it’s released into the air during the hair straightening process, it may come into contact with your skin or you may inhale it.
So ask your hairdresser what kind of keratin treatment is used before you book your hair appointment. Check the labels carefully. Ask if there are formaldehyde-free keratin treatments for straightening hair. These are more widely available in salons than ever before.
Avoid formaldehyde and other harmful chemicals if you’re pregnant or breastfeeding. Also, it’s best not to take babies or small children to salons where they may be exposed to chemicals in the air.
The best way to stop hair breaking is to maintain an aftercare routine by using hair products designed to care for keratin-straightened hair.
Every time you have a keratin treatment, your hair becomes more brittle and prone to breakage. Don’t have an in-salon keratin treatment more than three times a year.
Before getting into bed, brush your hair from root to tip for a few minutes. This helps distribute the natural oils throughout the length of your hair. Use a natural fibre brush.
Sleep with your hair loose. Don’t tie it up or clip it in place. You’re trying to keep it as straight as possible while you sleep.
Swap your cotton pillowcase for a super-soft silk or satin one. This will help reduce friction and frizz.
If you wake up with kinks and frizz in your hair, pass the flat iron over your hair a few times until it’s smooth and straight.
It’s quite common to feel like you have “greasy” hair after a keratin treatment. Don’t panic. Usually, this is directly related to how you care for your hair after the keratin treatment.
Your hair may feel oily and sticky because some people’s hair takes longer to absorb the keratin treatment. This will depend on your hair type and the brand of treatment used.
Curly, low-porous hair takes longer to absorb keratin. Be patient and give the treatment time to soak in.
Also, your natural oils may be making your hair feel greasy. Don’t wash your hair but you can use dry shampoo to refresh your roots.
The best time to colour your hair is before a keratin treatment. The treatment seals in the colour, making it last longer and appear more vibrant.
You should wait at least three weeks – preferably longer – if you choose to have colour applied after a keratin-straightening treatment.
Have your hair cut after the treatment. Your hair will have a smoother texture and will lie differently, so it should be cut then.
When you’re flat-ironing your hair, pull it upward and away from your scalp. Going upward, instead of straight back or down, will create volume.
