Posted by Usama Tariq on

Do you have treated hair? and you want to apply chemical treatment on your hair like Keratin treatment, Plex treatment or Rebonding?
Unfortunately you will not be able to do that. Here are the solution by Eazicolor with which you can apply hair care treatments easily.

Metallic hair

When Semi-permanent dye accumulates in human hair with frequent dyeing such type of dye makes your hair metallic.

Henna treated hair

Henna is typically used in powdered form mixed with water, it is then applied to your hair.  When we apply henna to our hair a coat or a layer of henna is spread all over the hair. Henna stains would last for a long period of time that’s why we cannot add any chemical effect because hair strands are filled with henna stains.

Coated hair

When we use color shampoos or oils all over hair it makes a layer on hair such type of hair is called coated hair. Color shampoo can form a strongly adhering coating on the hair surface and that’s why we cannot apply a chemical treatment to coated hair.

Why chemical treatments should not apply directly to metallic, henna treated, or coated hair?

Our hair is made up of cuticles and a cuticle is the hair’s protective carpet, composed of overlapping cells like fish scales. And when we treat our hair with henna, metallic or coated hair it leaves stains on the cuticles.

Chemical treatment reacts on the inner part which is called the cortex. The cortex of the hair is located between the hair cuticle and when the cuticle is covered with layers of metallic or henna treated hair so it is not able to have an effect on the cortex that’s why chemical treatment is not affected by that type of hair.

Methods to remove layers from cuticle

Bleach wash and bleach are the most effective methods to remove metallic, henna, and coated hair layers.


Use bleach powder with the developer (10,20,30) according to your hair demand 1:2 (1 spoon bleach with 2 spoon developer) and apply it to your hair.

Chemical hair treatments

Rebonding hair treatment

Rebonding involves chemically altering the structure of the hair. Hair Rebonding is a chemical process that modifies your natural hair and creates a clean, smooth, and straight style. It's also known as chemical straightening. Hair Rebonding is normally achieved with the aid of an authorized cosmetologist at your nearby hair salon

Hair Rebonding lasts up to 5 to 6 months when it is done by experts.

Note: - Avoid washing your hair immediately after Rebonding

Side effects

Rebonding may lead to hair breakage, damage, and dryness.

Relaxing hair treatment

Relaxing straightening involves a temporary change in the texture or shape of the hair. It is a hair straightening treatment that relies on a chemical process that softens tight cells and breaks down damaged hair strands.

Relaxing treatments are pleasant and suitable for someone who wants to ditch their wavy or curly hair altogether and have long-term super straight hair

Side effects

  • Chemicals can burn your scalp.
  • It may cause hair loss
  • Weaken the strands of hair if you are not taking care of it.


Difference between relaxing and rebonding

  • The main difference is that relaxing treatment does not make your hair fully straight. Whereas, rebounding makes your hair fully straight.
  • Relaxing treatment softens tight curls while Rebounding treatment breaks hair bonds.


Keratin is a protein treatment a fibrous protein forming the main structural constituent of hair feathers hoofs, claws, horns, etc.  Keratin works by smoothing down the cells that overlap to form your hair strands. The layer of cells is called hair cuticles. Cuticles absorb the keratin and make your hair look full and glossy.

If you have curly or wavy hair, keratin treatments can also make your hair straighter.

Side effects

  • Dizziness
  • Nausea
  • If treatment is done too often it can eventually lead to hair damage


Plex treatment

Plex is a protein treatment that works in the cortex of the hair to make and repair the bonds of the hair. It recreates and enhances structural micro-links, connecting fibers inside every hair. As a result, it improves hair quality and increases resistance against future damage.

Side effects

  • Nausea
  • Headache
  • Back pain

There are four types of plex treatment

  1. Ola plex

Ola plex is a three-step process that aims to rebuild the strength, structure, and integrity of your hair. It cannot damage your hair no matter how often you use it.

  1. Omega plex

Omega plex rebuilds the bonds in your hair and strengthens your hair strands and makes them less porous.

  1. Fiber plex

Fiber plex is a hair treatment that is used to protect your hair against the damage caused by lightening, lifting, and coloring.

  1. plex

Ph plex is a liquid that mix with hair color, bleach, and perms to protect the hair fiber from damage.


K-18 hair treatment

K-18 is a hair treatment mask for all types of hair that reconnects the broken keratin chains. It also restores hair elasticity, repairs split ends, and prevent hair breakage. K-18 strengthens hair’s core structure and helps restores damaged curl pattern.

K-18 is better than ola plex because it requires less use of products for results.
