Beautiful hair colour and soft curls can completely transform your look—but have you ever wondered why your hair often feels dry, rough, or brittle after a chemical service?
Hair colouring and perming work by changing the structure of your hair. While these treatments create beautiful results, they also weaken the hair if it isn't properly cared for.
At Dreamin’, we believe that understanding how chemical treatments affect your hair is the first step toward keeping it healthy, strong, and beautiful.
Let's explore why colouring and perming can cause damage and how you can protect your hair.
Understanding Your Hair Structure
Your hair is made primarily of a protein called keratin and consists of three layers:
- Cuticle – The outer protective layer.
- Cortex – The middle layer that contains protein, moisture, and natural pigment.
- Medulla – The innermost core (not present in every hair strand).
Healthy hair has a smooth, tightly closed cuticle that protects the cortex and locks in moisture.
Chemical services temporarily open and weaken this protective layer.
What Happens During Hair Colouring?
Permanent hair colour works by opening the cuticle so colour molecules can enter the cortex.
When lightening the hair, bleach or developer removes the natural pigment through oxidation.
Although this process creates long-lasting colour, it also:
- Weakens the cuticle
- Reduces moisture inside the hair
- Increases hair porosity
- Makes hair more prone to breakage
The more the hair is lightened, the more structural changes occur.
What Happens During a Perm?
A perm changes your hair's natural shape by breaking and rebuilding the internal bonds that give hair its strength.
During the process:
- The hair structure softens.
- Internal protein bonds are broken.
- Hair is reshaped around perm rods.
- New bonds are formed to hold the curl.
Although these bonds are rebuilt, they are often not as strong as the original structure, making the hair more vulnerable to damage.
Signs Your Hair Has Been Chemically Damaged
Common signs include:
- Dry or rough texture
- Frizz
- Split ends
- Increased breakage
- Hair tangles easily
- Loss of shine
- Hair feels weak or stretchy when wet
- Colour fades more quickly
These changes occur because the protective cuticle has been compromised.
Why Does Hair Feel Dry Afterwards?
Chemical treatments increase the hair's porosity, meaning it absorbs moisture quickly—but also loses it just as easily.
As a result, hair often becomes:
- Dry
- Brittle
- Difficult to manage
- More likely to frizz
Keeping chemically treated hair hydrated is essential for maintaining softness and elasticity.
Can Damaged Hair Repair Itself?
Unlike your skin, hair cannot heal itself.
Once the hair fibre has been chemically damaged, it cannot regenerate.
However, the right hair care routine can:
- Improve the hair's appearance
- Strengthen weakened strands
- Increase moisture retention
- Reduce breakage
- Smooth the cuticle
- Help protect against future damage
Regular trims remain the only way to permanently remove split ends.
How to Care for Coloured or Permed Hair
Choose Repair-Focused Hair Care
Look for products specifically formulated for damaged or chemically treated hair.
These products help strengthen weakened hair while restoring softness and shine.
Keep Hair Hydrated
Use nourishing conditioners and deep treatments regularly to replace lost moisture.
Hydrated hair is more flexible and less likely to break.
Limit Heat Styling
Hair that has already been chemically treated is more susceptible to heat damage.
Whenever possible:
- Lower styling temperatures.
- Use a heat protectant.
- Avoid unnecessary heat styling.
Handle Hair Gently
Avoid aggressive brushing or rubbing your hair with a towel.
Gentle handling helps minimise additional damage.
Healthy Hair Starts with a Healthy Scalp
Although colouring and perming affect the hair fibre itself, healthy hair always begins with a healthy scalp.
Maintaining a clean, balanced scalp creates the ideal environment for stronger, healthier new hair growth.
Supporting your scalp is just as important as repairing your existing hair.
