Best Hair Treatment – 7 Products to Repair & Restore Coloured and Damaged Hair

Last Updated: 16/10/2021

I tested 7 of the best-selling products and found Olaplex No. 3 to be the best treatment for bleached hair.

Having had my hair coloured since I was about 16 years old, it has endured just about the worst treatment you could imagine. From home dyes, sun-in, and bleaching the sh*t out of it with a concoction I made from Price Attack, it has seen it all.

While I still get my hair professionally coloured today, I ensure I have the right hair masks to repair, hydrate and nourish my blonde hair.

With this in mind, here are my picks for the best hair treatment for bleached, coloured or damaged locks.

Olaplex Hair Perfector No 3. is the gold standard when it comes to hair repair which is why it topped our list for the best hair treatment for bleached, coloured or damaged hair.

What makes No 3. so effective, is that it strengthens the hair from within. Olaplex does this on a molecular level, fixing the broken bonds in the hair and removing frizz, dehydration, and dullness. It leaves your hair feeling and visibly looking stronger and healthier. I personally use the Olaplex hair mask for my long, thick, and highlighted blonde hair and it works wonders.

The No. 3 Hair Perfector by Olaplex is actually not a conditioner but a home bond builder. In other words, it’s an at-home repairing treatment. It doesn’t contain any sulphates, parabens, or phthalates. Olaplex No. 3 is also vegan, cruelty-free, and nut-free.

The Olaplex No. 3 Hair Perfector is specifically catered to damaged hair. It brings back the appearance and texture of pre-bleached hair. If you’ve tried countless treatments to solve damage and breakage caused by bleach but didn’t get the results you wanted, I think it’s worth it to try Olaplex.

Next up on our best hair mask roundup is the Purple Hair Mask by Bold Uniq.

If we are talking bleached hair, then a purple hair mask had to feature on this list. While the brand itself is not a household name, you can’t argue with over 25,000+ reviews.

If you don’t know the benefit of purple shampoo, it basically works to neutralise the brassiness and yellow tones that come with bleaching hair.

What makes this one of the best hair masks, is that it not only keeps the brassiness at bay but also revitalises, strengthens, and repairs damaged hair.

Some of the key ingredients in the hair mask include Soy Protein, Vitamin B5, and a blend of super oils for conditioning and hydrating the hair.

If your bleach damaged hair needs some TLC and toning then apply this purple hair mask once a week. Brush through the hair with a wide-tooth comb and leave on for about 10 – 15 minutes for optimal results.

This hair mask has one unusual ingredient: quinoa protein. While you have probably heard of quinoa in the context of food, the quinoa protein in this product helps to strengthen damaged hair.

Our hair is made up of proteins, which are in turn made of amino acids. Dyeing and bleaching hair can weaken its natural protein levels, which is how you end up with brittle and dry locks. The damage also leads to dull, lifeless, and less vibrant hair.

Quinoa has an amino acid called cysteine which is lost in the bleaching and dyeing process. Quinoa also contains proteins, amino acids, and oils that repair the hair. That’s why the Aveda Intensive Treatment is specifically catered to people who’ve had their hair chemically processed and heat-styled.

With quinoa protein as its star ingredient, the mask works from the inside out to bring back life to the hair shaft. You’ll end up with silky, smooth locks.

Organic jojoba and castor oils are rich in lipids which deliver extra nourishment to the hair, shielding it from damage.

To further intensify that self-care experience, the Aveda Intensive Treatment has an alluring aroma made from organic bergamot, mandarin, ylang-ylang, and other pure flower and plant essences.

It’s also Leaping Bunny-certified so you can be assured it’s not tested on animals.

Be aware, Damage Remedy Treatment contains silicones. So if you’re looking to avoid it, this might not be the best hair mask for you.



4. Moroccanoil Intense Hydrating Hair Mask

The Intense Hydrating Hair Mask by Moroccanoil is part of their range of hair masks for specific hair needs. This one is medium to thick hair types and suited for especially dry hair. It will improve your hair’s texture and manageability.

The main ingredient is Argan oil, which is famous for its nourishing properties. It’s rich in tocopherols (Vitamin E) which promote healthy hair growth. Argan oil is also filled with essential fatty acids and antioxidants which support your hair’s health.

The Hydrating Mask wards off static because of an anti-static ingredient called Behentrimonium Chloride.

These ingredients make for a nutrient-packed, creamy hair treatment that you can use for 5 minutes with great results. You’ll notice effects on how your hair feels, how elastic it is, and its overall shine and manageability.

This hair mask also smells luscious. It has an aroma that’s sweet and flowery with notes of spicy amber and musk.

Because of how rich this treatment is, it will weigh down your hair if you overuse it. To cut through the thickness, you can use a clarifying shampoo to remove buildup. Women with fine hair may find this weighs the hair down.



5. Sachajuan Hair Repair

The people at Sachajuan sure know how to make good products. And I’m not just talking about what’s in the bottle–the bottle itself looks minimalist but chic. I’m partial to the convenience of a pump bottle. One purchase gives you 250 ml of product perfect for treating bleached and blonde hair.

Sachajuan is a Scandi brand from Stockholm and its products have something called their Ocean Silk Technology. It’s what makes them different from other haircare brands. This technology uses two coldwater algae extracts. One works inside the hair, strengthening it and delivering minerals like magnesium, calcium, manganese, and zinc. The other algae extract takes care of the hair surface, giving it shine and preventing damage. The result is a miracle hair mask.

Their hair philosophy focuses on the basics. They believe simple is better. This line would be good for those who have overloaded their hair with products and want to pare down their routine. This mask would also be good for those looking for simple, natural, and effective ingredients.

The Sachajuan hair mask is a concentrated treatment that’s best for damaged and stressed tresses. Because of its cell-regenerating benefits, you get stronger, smoother hair for longer.

I am always sceptical of products pushed by influencers, but when it comes to the Coco & Eve Like a Virgin Hair Mask, I have to say the hype is valid. This is one of the best hair masks for most hair types.

This deep conditioning mask is suited to all hair types, but it is the ultimate hair hero for those with bleached damaged hair. The miracle hair mask works to hydrate, condition, improve hair texture and shine, treats split ends and tame frizz.

The hair mask is packed full of ingredients that sound good enough to eat. Dry hair is nourished with a mask formula of raw virgin coconuts, argan oil and shea butter.

If you have hair in need of some serious TLC, swap your normal conditioner out twice a week for the Coconut and Fig hair mask and apply it to damp hair for 10 minutes. Rinse out and style as normal.

Best of all the mask contains no nasties. That means no sulphates, no parabens or phthalates.



7. Christophe Robin Shade Variation Mask in Golden Blonde

A recent addition to the list is the Shade Variation Mask by Christophe Robin. This is one of the best hair masks for those who want to amplify their highlights and blonde tones but also nourish and restore dry or brittle hair.

This deep treatment can be used between hair dressing appointments to enhance dull blonde hair that has faded or become transparent. In tandem, the mask works to reinvigorate and deeply nourish hair that has been damaged from regular styling and colouring.

Use the hair masque once a week for super soft and shiny results.



A Guide To Achieving Healthy Hair


Olaplex No.3


How can I make my hair healthy after bleaching?

When your hair starts to feel like straw, it’s time to double up on the TLC and invest in quality hair masks. You need good haircare products whatever hair you may have, but especially if you have color treated or brittle hair. Here are some tips I’ve found that worked.

Protect your hair from UV rays.

SPF isn’t only for your skin. Your hair also needs protection from the damaging rays of the sun. These rays can even turn your blonde locks into a brassy hue. You’ll also want a hat or scarf as double protection from direct sunlight.

Use shampoo and conditioner designed for coloured hair.

Colour-safe shampoo and conditioner are designed to make your bleach and colour last, as well as prevent damage. Make sure to apply lots of conditioner because your hair will suck up that moisture like a straw.

Say goodbye to sulphates.

Experts recommend using products free from sulphates. These chemicals are harsh and will strip out hair. Instead, you can alternate between moisture-rich and protein-rich shampoo formulas.

An ideal time between washes is 2 days. Don’t take too long between shampoos because your ends will end up brittle which can lead to split ends. In between washes, dry shampoo is your friend for battling oil and dirt.

Use a deep conditioner or hair treatment.

A regular conditioner just won’t cut it if you have hair that’s been soaked in bleach. You’ll need something more nourishing on top of that conditioner. You can even have a deep conditioner to replace your regular one. Deep conditioning with hair masks helps strengthen, hydrate, and smoothen hair.

Use a tinted shampoo on your hair to remove brassiness post-bleach.

To prevent your hair from turning into that dreaded yellow colour, use a purple shampoo. These are formulated to tone colour treated hair.

Use it on wet hair, like a normal shampoo. Rinse with cool water afterwards to seal the cuticle. The results: platinum, icy blonde hair.

Apply a leave-in conditioner.

You may think this is too much conditioning but damaged and dry hair needs all the hydration it can get. Bleach is one of the harshest chemicals you can put on the hair, after all.

Apply a leave-in conditioner to damp strands (not wet hair) to seal in moisture, concentrating on the mid-lengths to the ends of the hair. Do not wash it out. These will make sure the moisture stays locked in the hair.

Protect your hair when heat-styling.

If you can’t forego hot tools when styling, make sure you get a high-quality heat protectant. They serve as a barrier between your hair and the heat. Remember that bleached hair is already prone to breakage and heat styling tools can easily cause more damage if the hair is not protected. Heat protectants are full of silicone which can make your hair smoother and prevent moisture loss.

What is the best product for damaged bleached hair?

The products mentioned above are the best in treating damaged hair, prevent split ends, remove frizz and give your hair shine and strength. However, to give your damaged tresses a new lease on life, quality hair masks hair and treatments will work best.

A hair treatment is also called a hair mask or deep conditioner. They give a shot of moisture deep into the hair strands, which is more than your average surface-level conditioner can do. They strengthen and repair hair so they grow healthier and softer.

The best hair mask is made with nourishing ingredients such as coconut oil, avocado, argan oil, biotin, shea butter, keratin, and plant-based proteins. Bleach strips away so much from your hair and powerful treatments can replenish moisture in a single-use. Use only the best products and ingredients on your hair so you can reap amazing results down the line.

These hair masks are meant to be left on the hair for longer than a usual conditioner. For best results, use a hair treatment at least once a week, around 30 minutes or even longer. Some leave them on overnight to soak in all those highly concentrated nutrients.

What’s the best way to use a treatment product on bleached hair?

Hair mask instructions can vary with different brands and products. Depending on the condition of your hair, use your favourite hair mask twice a week to restore and strengthen the hair.

Usually, after your hair is mostly dry but still damp, you scoop out enough conditioner to cover your hair and massage the product through the lengths of your hair. Concentrate on the tips of your hair because that’s where you need the most nourishment. Be thorough in your application.

If you want to, you can use a wide-tooth comb to gently comb through the hair to distribute the mask well. Afterwards, you can pile your hair up and cover it with a shower cap or some sort of plastic. Set a timer and wait for the mask to sink in the hair shaft. You may also opt to leave it on overnight.

Finally, you can wash the conditioner out using cool or lukewarm water.

Wrap Up

If you’re hoping to soothe the damage from overenthusiastic bleaching of hair or looking to repair strands that have seen better days, any of these hair treatments will fit the bill.

With that said, Olaplex No. 3 is my personal favourite and I am not alone. It is easily considered the best hair mask on the market. We can forgive the price tag for a 100ml bottle because it actually is effective in strengthening and repairing damaged and dry hair. Overall, it’s worth the investment.

This product is perfect for colour treated hair needing an SOS but ultimately can be used for most hair types.
