How To Repair Chemically Damaged Hair?

hair colouring with chemical dyes


In the modern world of hair fashion, it may be exhausting to search for a product that does what’s promised.

Your hair is not alive!

It doesn’t have a nervous system or blood flow.

If it gets damaged, you can’t just let it heal on its own without some help from products like oils and conditioners that contain hydrolysed proteins.

So if you want your hair to look shiny and healthy all day, you need to do regular maintenance by using these products every day.

If you have hair chemically damaged, I will give you 8 tips to help.

Identifying damaged hair.

Hair damage is a common problem that can occur on its own or as an unfortunate result of other sources.

Your hair will get dry when the cuticle is damaged.

This damage can also happen from brushing your hair.

If your hair is damaged, the cuticle can cause split ends.

The break happens at both ends on the strand of your hair.

Breakage occurs when there is too much damage, and weak spots form along the strands themselves, which causes them to break.

If you style your hair without enough protection, it can lead to permanent follicular loss.

8 tips on how to repair chemically damaged hair

1. Avoid using products containing harmful chemicals.

Chemical hair dyes are a popular way to colour your hair. However, they can also damage the health of your hair.

These chemical treatments will cause hair dryness and breakage within the strands, which could lead to fuzziness and split ends.

Your chemically damaged hair may be troublesome to style, and less shiny than healthy hair.

Likewise, your damaged hair can increase the risk  scalp dermatitis (dandruff).

Poisonous parabens, polyethylene glycol and formaldehyde are just some ingredients used in most shampoos and dyes which will do significant harm when left on your hair for too long or if you don’t rinse out properly.

Based on the GCC website, there are 8 toxic products in an inventory of chemicals to avoid.

• Sulfurates – Ammonia Lauryl Sulfate, Sodium Laureth Sulfate and Sodium Lauryl Sulfate
• Parabens – butylparaben, ethylparaben, and methylparaben.
• Polyethylene Glycols
• Triclosan
• Formaldehyde
• Fragrances Colors
• Dimethicone
• Retinyl Palmitate

If you are unsure of any chemical listed on any labels of beauty and hair care products, check it on EWG’s Skin Deep.

2) Apply conditioner after every shampoo.

It’s important to take care of your hair, especially when it involves conditioning.

Too much can do more harm than good so you would like to keep conditioning your hair to a minimum of once per week.

Be warned that too many washes can also dry out your strands.

Many women find that conditioning their hair more than once or twice per week is too much, as this may cause over-moisturized locks.

You will need a detangling session every week to take care of your hair.

To take care of your hair, use serum or conditioner that can help hair be soft and shiny.

3. Use a deep conditioning treatment once a week.

The goal of a deep conditioning treatment is to keep your hair healthy and moisturized.

Deep conditioners help hydrate and soften your damaged hair. It also improves your hair in stretching and tension, as well as fighting off hair breakages.

Deep conditioning treatment can help your hair untangle any knots, decrease frizz from the roots, and restore natural oils for silky-smooth locks!

Look for ingredients such as avocado oil, coconut oil, argan oil or shea butter – these will deeply penetrate your strands while working their way through those pesky tangles.

4. Start washing with cool water rather than hot water.

No one knows if cold water is better than hot water for your hair. Some sources say it’s more effective, others believe the opposite.

While hot water opens the pores and unclogs hair follicles.

It also may damage your scalp, preventing hair growth.

Coldwater, on the other hand, doesn’t dry out the sebum layer, which is a natural lubricant barrier of your hair.

The best way to wash your hair is to use lukewarm water, and then follow up with a cool rinse.

This will help keep your hair strong while keeping it clean without drying out the scalp.

Using this method of washing will help keep your hair healthy and robust, so you don’t have to worry about breakage.

According to Dr. Zeel of, – “You can use water at 100 °F or 38 °C (slightly above the normal body temperature) to wash your hair. During summer, you can use water at a lower temperature. After shampooing and cleaning with lukewarm water, it is better to give a final rinse using cold water at a suitable temperature. This will help locking the open pores and elevated cuticles.” 

5. Brush your hair less

Brushing your hair after a shower appears harmless, but you could damage locks without knowing it.

This is because your hair tends to swell when wet, and this makes your hair more fragile and prone to breakage.

Hair that is swollen and tugged on by brushes will snap off, leaving baby or fine hair behind.

This can lead to dryness and fuzziness in the future. Over time, it may also lead to a greater risk of developing split ends.

I recommend using a combing brush with wide pins spaced apart.

The pins should not be too close together or too far apart.

With this type of brush, your hair will get the oils from your scalp all over it, and you will feel comfortable when brushing it.

Choose your brushes with bristles that should feel soft against your skin for a gentle brushing experience.

6. Avoid blow-drying or flat ironing your hair. 

Blow drying will make your hair straight, voluminous and natural looking.

You need to use a heat protectant first.

If you want, you can also blow dry it for a few days to ensure the effect is satisfactory.

Alternatively, you may want to watch video tutorials to learn how to blow-dry your hair.

Flat ironing does more than flatten out kinks in your tresses – it offers them that sleek Hollywood fashion that stays put all day long.

However, exposes strands of fine hair to direct heat could be bad news on multiple levels because it can damage your hair.

If you need flat ironing, first brush your hair and opt for the occasional low heat.

Don’t forget to use a decent protectant.

When attainable, avoid the heat altogether and let the air do all your hair’s work for you by gently wrapping it in a towel after showering.

This will help pull out excess water before letting your hair hang dry without rubbing with the towels!

7. Only dye your roots.

Chemical treatments may be damaging, especially if they’re applied too often.

To prevent damage and maintain a healthy head of hair while getting your desired colour result, simply touch up the root with a lighter shade dye.

It is a good idea not to dye the remaining of your hair for a few days, as this will help it heal.

8. Shield hair from the sun.

Shield your hair from the sun with products containing UV filters.

Sun exposure can cause split ends, so trimming regularly is a must during the summer months to avoid more damage on top of existing problems.

Keep your tresses hydrated by using the moisturizing product, and take care not to overdo it in chlorine or salt-filled environments.

One of the best ways to shield your hair from the sun is to go for a more subtle, natural style.

You can achieve this with Bobby pins or clips to pack less heat on top of your head and put on a hat for protection.

Protect your coloured hair.

If you have coloured hair, it’s important to use colour protecting products like shampoo and conditioner.

This will help protect your hair against the sun during summer months.

In the summer, you want to use your blower less.

Instead, take advantage of the warm weather breezes to dry your hair.

You can do that by getting creative with your hairstyle and using extra protection against UV rays.

How long does it take to repair chemically damaged hair?

Chemically damaged hair is a problematic issue for many people.

If your conditioner or other products that usually help with the problem aren’t working, go to the doctor.

They can do tests and see if there is something else wrong.

The good news is there are steps you can take to repair the damage and give yourself some relief.
