Tips on How To Flat Iron Thick Hair:

Straightening thick hair is not an easy process but if you prepare hair in the right way and use the right straightening iron then you will be able to achieve smooth, shiny, and straight hair no matter how thick it is. So, below is a step-by-step guide on how to flat-iron your thick hair properly:

  1. Wash and condition your hair: you will have to first wash your hair with a gentle shampoo in-order to avoid stripping it before using heat over it. Afterward, apply a straightening conditioner with moisturizing ingredients to the hair in order to ensure that it’s properly hydrated and smooth. On other hand, you may wash your thick hair with a moisturizing shampoo for added hydration in case your naturally-thick hair tends to be dry.


  1. Towels dry your thick hair: after washing and conditioning your hair, use a microfiber towel to dry it until it feels damp. In fact, having partially-dry hair will help you achieve fast blow-drying results. Additionally, using a microfiber towel is great for drying thick hair and these towels even have a more absorbent and softer material than traditional cotton.


  1. Apply a heat protectant

    : it’s very important to protect your hair locks just before blow-drying or straightening them because heat can be very damaging to natural hair. So, heat-protectant will help to coat your hair so that it doesn't burn or dry out during the styling process. In fact, heat-protectant are available in different types which include; sprays, lotions, and creams but creams work best for naturally-thick hair. Additionally, Argan-oil can also work as a heat protectant but don’t apply too much because this may weigh down your hair. So, just lightly coat your hair with any given heat-protectant, and don’t apply it to the top of the head/scalp.


  1. Blow-dry hair with a round brush: Thick hair actually requires extra work to straighten and that’s why it’s very important to first blow-dry while brushing through it with a round bristle brush. This actually helps to smoothen and straighten hair so that you won’t need to over-use a straightening iron to achieve great results. However, make sure that your hair is completely dry before using a flat iron over it.


  1. Divide hair into sections: it’s very easy to straighten hair that has been divided into smaller sections especially if it has a thick texture. So, begin by dividing the hair in half and then clip the top section to your head. Afterward, divide the lower half into sections that are approximately 1-to-2 inches wide depending on the size of your irons plates. In fact, the thicker your hair is, the more sections you should create for the best straightening results.


  1. Choose a flat iron with variable heat settings: most flat-iron are only equipped with a low, medium, and high setting but its best to get a flat iron that allows you to choose a precise temperature because you may want to use the lowest amount of heat to straighten your delicate natural-hair and this can only be achieved by selecting a specific temperature-setting. However, for thick, coarse hair, it’s recommended to set your flat iron between 350 and 400 degrees for best-straightening results and this implies that you will need to get a flat iron that is adjustable to that specific temperature range.


  1. Heat the flat iron:

    after switching on the flat iron and selecting the right heat setting, wait for a few minutes for the flat iron to heat up to the right temperature. In fact, most flat irons will alert you when they reached the proper temperature by either making a beep or lighting up at a certain spot. All in all, wait until the flat iron is full-heated before using it on your hair because low temperatures on your hair aren’t good since it requires you to go over the same sections of hair more than once in order to achieve a completely smooth result.


  1. Move the flat iron in a fluid motion: you will have to quickly glide the straightening iron over each section of hair starting approximately a half-inch below the roots of your hair. Remember to keep the pace steady so that the flat iron doesn’t generate uneven areas in certain spots. Additionally, keep in mind that you may have to go over the same section of hair more than once in order to achieve complete straightening results.


  1. Get closer to hair roots at the crown section: when you approach the sections of hair at the crown of your head, you will need to adjust the straightening movements by simply lifting the sections away from the scalp in order to get the straightening iron closer to the hair-roots and after pulling the flat-iron outward from the head in order to achieve the smoothest finish. Lastly, you will need to press firmly as you move the flat iron over your hair and outwards from your head so as to ensure that your hair is as straight as you need it to be.


  1. Apply a hair-shine product: you should consider applying a silicone-based shine product to your hair after straightening it in order to achieve that nice glossy appearance. in fact, for those with thick hair or coarse hair, a serum will work best for them but only apply a small amount to your hands and then lightly smooth it over the length of your hair in order to coat all the strands of hair on the upper layers. However, don’t apply too much shine serum because it may make your hair look greasy and the roots of your hair won’t need any shine serum because they are the healthiest part of the hair.

So, consider putting on an old T-shirt, disposable cloves, and an old towel over your shoulders in order to guard yourself against spilling hair chemicals.


  1. Pick a Hair-relaxer and mix it up: straightening hair with a relaxer actually helps to prevent the development of curls within it. So, go to any make-up or hair-supply store a pick a hair conditioner that works well for your hair type.

  1. Apply Vaseline along the neck, hairline & ears: if you want to protect your skin from soaking into chemicals, apply a thin layer of Vaseline on all edges of your hairline. In fact, it’s not good for your skin and eyes to contact the hair relaxer because it may lead to serious health issues.


  1. Do a strand test: you will need to apply a hair relaxer to a particular section of your hair and then leave it on until you see results. Afterward, wash off the relaxer and dry your hair in order to see whether there are any breakages or damage. If the relaxer works well for your hair then continue applying it all over the entire head of hair.


  1. Apply the relaxer to the whole head of hair

  1. Smooth through the hair with a comb: after applying your relaxer, use a wide-toothed plastic comb to go through your hair in order to even out the relaxer. This will help to ensure that every strand is well-coated with the relaxer from the roots to the tips.


  1. Set the timer: it’s recommended to leave the hair relaxer on for an appropriate amount of time. So, read the instructions that come with the relaxer package in order to know the maximum amount of time a relaxer should be soaked into your strands. However, make sure that the relaxer doesn’t overstay within your hair because this can lead to serious damage.


  1. Rinse, shampoo, and rinse your hair again: when the recommended time is up rinse your hair thoroughly with clean water in order to get rid of the relaxer. Afterward, apply shampoo to your hair and then it out again in order to remove every last residue of hair-relaxer.


  1. Apply a hair conditioner: many relaxing kits include a leave-in conditioner. So, apply this conditioner to your hair after washing out the relaxer. In fact, conditioners help to seal the hair and even prevent damage but make sure that all the layers of your hair receive the conditioner and afterward towel-dry your hair.


  1. Style your hair straight: afterward, your hair will look straight but consider brushing through it in order to make it look sleek and smooth. However, there are multiple straight hairstyles that you may try out on your hair at the stage.
