Step One

Hair needs to be washed first to get it ready to add a good straightening conditioner it. Clean hair makes the whole straightening process better. If you haven’t got time to wash your hair, even dry shampoo can be used. This will add shine as a starter. Remember that it’s not just any shampoo or conditioner which will give you the look you want.

You will have to select the right one, something like what everyone loves and knows, something professional for example the L’Oreal products. If it doesn’t suit your hair, try and pick another good brand that you might be familiar with.

If your hair has been dyed before, you will need a straightening shampoo that’s got sodium lauryl sulfate in it and sodium laureth sulfate to keep your color well.

Step Two

After washing and conditioning, apply the hair straightening serum. The right one for your particular hair type will work wonders. It is a good idea to add the serum while your hair is wet because then it is able to spread evenly into your hair without clumping the chair.

Comb gently through your hair using a wide-toothed comb. Start from the hair roots to the tips, with more volume added to the hair tips. Evenly distribute throughout all the hair strands. You can air dry your hair now for about 5 minutes or so. Air-drying is making your hair dry via unheated air.

Lovely products such as argon nut oil, Moroccan oil, and coconut oil are also examples of products that will help with keeping your hair hydrated during the course of the day. Any products that have silicone in them will also contribute towards keeping your hair straight.

Blow-dry your hair, not with a hair dryer, but with a blow dryer. Once again, it is not just any blow dryer to blow-dry your hair. A high-quality one will seal your hair and keep it clean and straight for longer. If you blow dry your hair more than once a week. Then you also need to add a moisturizing mask before using your dryer and flat iron. The blower drier should be about 1500 watts while drying with your round brush.

Step Four

You would have turned your flat iron to prepare to straighten your hair. Make sure that you did not go over the correct temperature that is suitable for your hair. A good guide is if you have light and fine hair, the heat should usually be on the low setting while thick and curly hair will require a high heat temperature.

For in-between type hair, the medium heat setting will be suitable.

If your hair is prone to damage, don’t take the risk of ruining it further; know which temperatures apply for your kind of hair type when you want to straighten hair with a flat iron.

The next step is to put up all your hair, holding it back with a hair tie or clip. Just leave the bottom layers available, because this is where you are going to start with your hair.

  • You should try and place the straightener as close to the roots of the section you have chosen, but just don’t burn yourself. It means you will probably start straightening about an inch away from your scalp.
  • Straighten your bottom layer and maybe even the next layer, going over them only once with your flat iron.
  • When you are finished straightening the bottom part, you will let down another layer of hair for strengthening. You will repeat this until your whole head of straightening hair process leaves your hair straight and sleek.
  • You do it by clamping the hot iron down so that each of the heated blades touches your hair resting between.
  • Don’t clamp too tightly so as to avoid creating a ridge in the hair where you start to straighten. Also, don’t hold the iron in a certain spot for too long because that can also cause a ridge.
  • Now run your flat iron down from the top down to the hair section. Move with fluid movements from the hair roots to the ends of your hair. Remember not to hold the straightener in any area for too long to prevent ridging.
  • If your hair is very thick you might have to go a few times. The strength of the flat iron will also determine the number of times you go over the section of hair. Basically, the lower the setting, the more times you will go over the hair.
  • If you see steam coming from your flat iron, don’t panic, it is caused by the hot iron contacting with the moisture that was left over in your hair. If you smell burning hair though, turn the settings down straight away.
  • Once you have got the section of hair straight, move it out of the way and unclip the next layer ready to straighten the hair. Things are easier if you move around your head from side to side rather than just selecting any piece of hair and straightening it.

If your hair tends to get frizzy, put on a hair spray or some setting serum after completing a section.

Try not to get hair products on hair that you have not straightened yet because these products can actually negatively influence your process of hair straightening and can cause damage to your hair. Here is the list of flat irons you can choose if struggle with, how to straighten damaged hair.

Hair spray is added to the hair. It is vital as well because it locks in all the straightening processes you have undertaken with your hair, and it protects the hair too from the weather and pollution.
