  • Hydrolyzed keratin proteins moisturize and strengthen hair


This hairspray by Joico sells at around $16 for ten ounces, so the price isn’t that bad at all.

The spray gives your hair moisture and shine, and can be used to blow-dry, flat iron or even to set a finished style!

It provides all-day hold with no stickiness and is a great choice if you want to flat iron your hair and then curl it or do an up-do.



Illumai Vibrant Primer Mist

  • With dihydroxypropyl peg-5 linoleammonium chloride extracted from vegetables, it will prevent tangling and thermal heat damage.


The Illumai Vibrant Primer Mist is another lightweight heat protecting spray. It’s ideal for all hair types, whether ethnic, straight or color-treated, and even extensions!

It’s easy to use and can cut your styling time in half by making your hair easier to work with.

This spray conditions hair while protecting it, adding shine and moisture. It can even be used to detangle your hair before flat ironing!

However, this product is on the expensive side – about $22 dollars. Also, it’s free of silicones, which means there isn’t that essential barrier between your hair and the heat.

This opens your hair up to the risk of being damaged or fried by your flat iron.

The mist has great features and makes hair feel healthy, but for the price and the lack of silicones, it may not be the best choice for fine or ethnic hair.

It sells at about $16 for 8 ounces, which isn’t cheap but isn’t expensive either, but this spray can give hair a dry, tangled feeling.

It doesn’t have much slip, so it can be difficult to comb through hair with or to blow-dry with.

  • Internal moisture of your hair starts to evaporates, yes they are leaving.
  • The chromophores, which define how to shine your hair is, are about to degrade.
  • As long as the hair is exposed to high heat, the hair structure, and its surface breaks, radically.

It even becomes worse if you straighten wet hair.
