Let’s be real—there’s nothing wrong with wanting silky straight hair, vibrant color, or those juicy curls from a perm. But if your chemically treated hair is feeling like hay, breaking off faster than your last situationship, and refusing to grow past your shoulders, we gotta talk. Chemical treatments can be a game-changer for styling, but they can also be your hair’s worst enemy if you’re not careful.
So, why exactly does chemically treated hair have more breakage? And more importantly, how can you keep your hair healthy while still rocking your favorite looks? Let’s break it all down—scientifically and practically.
The Science Behind Chemical Hair Damage
Chemically treating your hair means you’re changing its natural structure using powerful ingredients. Whether it’s relaxers, perms, bleach, or permanent dye, all of these treatments break down the natural proteins in your hair to achieve the desired effect. And the main protein under attack? Keratin—the building block of strong, healthy strands.
- Relaxers & Perms: These work by breaking down the disulfide bonds in your hair, the same bonds that give it strength and elasticity. Once those are altered, your hair becomes permanently straighter or curlier, but also weaker.
- Bleaching & Hair Dyes: These treatments lift the hair’s cuticle (the outer protective layer) so the chemicals can penetrate and change the pigment. But when the cuticle is lifted too much, your hair loses moisture and becomes rough, leading to breakage.
- Keratin Treatments & Brazilian Blowouts: While they sound like they’d be good for your hair, most of them contain formaldehyde or similar chemicals that can over-process and weaken your strands over time.
When the protein structure of your hair is damaged, your strands lose elasticity, become dry, and snap easily. And sis, nobody wants to be out here with thinning, brittle hair.
Signs Your Hair is Suffering from Chemical Damage
Not sure if your hair is crying for help? Here are some telltale signs: ✔️ Excessive shedding or breakage (especially when detangling)
✔️ Dry, brittle texture that feels rough instead of smooth
✔️ Split ends that keep coming back no matter how often you trim
✔️ Lack of elasticity—if you pull a strand and it snaps instead of stretching, that’s damage
✔️ Increased tangling because your cuticle is raised and rough
If you’re checking off most of these, your hair is waving a red flag, and it’s time to make some changes before it gets worse.
How to Prevent Breakage in Chemically Treated Hair
Just because you color, relax, or perm your hair doesn’t mean it has to break off. Here’s how to keep your chemically treated hair strong and flourishing:
1. Strengthen with Protein Treatments
Since chemical treatments break down the natural proteins in your hair, it only makes sense to give them back! Look for deep conditioners with hydrolyzed keratin or silk proteins to rebuild strength. But don’t overdo it—too much protein without moisture can make hair stiff and prone to breakage.
2. Deep Condition Like Your Hair Depends on It (Because It Does)
Moisture is key! Chemically treated hair loses its natural moisture faster than untreated hair, so a deep conditioning routine is non-negotiable. Use a rich, moisturizing deep conditioner once a week to keep your strands soft and elastic.
3. Lay Off the Heat
Girl, put that flat iron down! Chemically treated hair is already weak, and excessive heat just makes it worse. If you must use heat, always use a heat protectant and keep the temperature low.
4. Trim Those Ends Regularly
Split ends travel upwards if left unchecked, causing more breakage. A light trim every 8-12 weeks will keep your ends fresh and healthy.
5. Avoid Overlapping Chemical Treatments
If you’re relaxing or coloring your hair, make sure you’re only applying the chemicals to new growth—not already treated hair. Overlapping chemicals on previously treated strands leads to overprocessing and severe breakage.
6. Use a Sulfate-Free, Moisturizing Shampoo
Sulfates strip the hair of natural oils, which chemically treated hair desperately needs. Stick to gentle, sulfate-free shampoos that cleanse without drying your hair out.
7. Protective Styling is Your Friend
Give your hair a break with low-manipulation styles like braids, twists, or wigs (with proper edge care, of course!). Just don’t keep styles in too long, or you’ll cause more harm than good.
8. Nighttime Care is a Must
Cotton pillowcases soak up moisture from your hair, making breakage worse. Sleep with a satin or silk scarf or bonnet to keep your strands hydrated and protected overnight.
Modern Alternatives to Traditional Chemical Treatments
If you love the look of relaxed or colored hair but want to avoid extreme breakage, here are some safer alternatives:
- Silk Press Instead of Relaxers: Gives you the sleek look without permanent chemical damage.
- Henna or Semi-Permanent Dyes Instead of Bleach: Less damaging and still gives vibrant color.
- Heatless Styling Methods: Flexi rods, perm rods, or banding to stretch natural hair without chemicals.
- Wig & Weave Slayage: If you want a new look without commitment, high-quality wigs and weaves can be a great option.
Final Thoughts
Chemically treating your hair doesn’t mean you have to accept breakage as a way of life. With the right care, products, and a little patience, you can keep your strands healthy while still enjoying the styles you love.
Remember: Healthy hair is happy hair! Treat it right, and it’ll thrive—whether relaxed, colored, permed, or natural.
