Is a Keratin Treatment Kit Safe for Colored or Damaged Hair? Expert Insights

19/09/2025

Why the Question Matters

In Saudi Arabia, hair goes through a lot. From the colouring sessions before weddings and Eid, to the daily blow-drying, to long hours under the sun and humidity — it all takes a toll. Fragile strands become tougher to manage, and coloured hair tends to lose its glow faster than you’d like.

This is why many women hesitate to try a keratin treatment kit at home. The worry is simple: will it help or make the damage worse? Experts agree that when used correctly, a keratin kit can do the opposite of harm. It restores strength, protects colour, and helps hair cope with daily stress.

Why Coloured or Damaged Hair Needs Extra Care

Once you colour your hair, it doesn’t stay as strong as before. Bleaching especially—because it lifts the cuticle, leaves it open, and then the strand just breaks easier. Even dark dyes take their toll, more so when you keep touching up the colour every few weeks. Add daily heat from blow-dryers and straighteners, and hair quickly starts to lose its natural keratin.

Even hair that hasn’t been coloured can end up just as damaged. It becomes dry, splits at the ends, and tangles easily. In Saudi Arabia, the sun and humidity make this worse. Hair turns frizzy and dull, no matter how much oil or conditioner is used.

That’s why many women think about using a keratin treatment kit. But the real question is: is it safe?

What a Keratin Treatment Kit Does

keratin treatment kit works by putting protein back into the fibre. It fills the gaps caused by colouring, bleaching, or heat. Once these spaces are sealed, the cuticle lies flatter. That’s why hair reflects more light, frizz reduces, and styling becomes easier.

It’s important to know this is not the same as chemical straightening. Keratin doesn’t break the bonds inside hair - It supports them. A keratin hair straightening kit makes hair look straighter mainly because the smoother cuticle leaves less puffiness. In reality, it’s more of a repair treatment than a harsh chemical change.

Safety for Coloured Hair

One concern is whether keratin strips colour. The opposite is true when a good formula is used. When hair is coloured, it soaks up water too quickly and lets colour slip out just as fast. That’s why shades fade. Keratin steps in by filling those tiny holes and closing the cuticle, so the colour holds on longer. Many women notice their shade stays brighter after a keratin treatment.

Timing still matters. Experts usually advise leaving around two weeks after colouring before you do keratin. It gives the shade time to settle and reduces the risk of patchy tones.

Safety for Damaged Hair

You can tell that you have damaged hair through split ends, breakage, or rough texture. This happens when the natural keratin inside the fibre is missing.

A keratin treatment kit replaces some of what’s lost. It strengthens weak areas and helps hair resist daily stress. With repeated use, strands feel stronger and smoother, and split ends become less frequent.

For very over-processed hair — the kind that breaks in clumps or feels like straw — keratin should wait. In those cases, start with repair masks before moving on to keratin.

 

Using a Keratin Treatment at Home Kit

The appeal of an at-home keratin treatment kit is simple: it saves time. Instead of hours at a salon, the process can be done step by step at home.

Here’s how it usually works:

  • Start with a clarifying shampoo. This clears away any build-up so the hair can actually absorb the treatment.
  • Apply the product to damp hair, moving section by section until everything is covered.
  • Use moderate heat — about 180–200°C — to seal it in. Too much heat can harm the fibre, so steady and controlled is better.
  • Next step, switch to sulphate-free shampoo and conditioner. Regular formulas strip the treatment away too quickly.

It may feel like a bit of work at first, but the payoff is worth it — smooth results that can last for weeks, even months. And in Saudi heat, that’s fewer battles with frizz and the comfort of knowing your style will actually last through the humidity.

Choosing the Right Kit

The formula matters. Cheaper kits sometimes contain harsh chemicals that dry hair more. Professional kits with Juvexin, GK Hair’s keratin blend, are designed to repair and protect.

One option is The Best Keratin Professional Hair Kit, which delivers salon-level smoothness but is safe for coloured or fragile hair.

Keratin Treatment Kit Price: Cost vs. Value

Salon keratin treatments work well, but they are expensive and time-consuming. Many women only do them once or twice a year.

When you buy a keratin treatment kit, you get similar results at home for less. One kit can last for several applications, depending on hair length and thickness. That makes it a better value compared to repeating salon visits.

Maintaining Results After Treatment

How to keep the results for longer:

  • Wash your hair with a special shampoo, a sulphate-free one. Usual formulas strip the treatment too quickly.
  • Once a week, use a deep conditioner to keep the fibre strong.
  • Before using heat tools, add a leave-in spray or cream for protection.
  • For daily use and precaution measures, a drop of Argan Oil Serum smooths the hair and controls flyaways.

With these small steps, the smoothness lasts longer, and the hair keeps its strength and shine.

Expert Advice: When to Be Careful

Most women can use keratin kits safely, but there are a few cases to be careful of:

  • Don’t apply on hair that is breaking heavily — repair first.
  • Do a patch test if you have a sensitive scalp.
  • Avoid low-quality kits at all costs; they may contain strong chemicals.

Final Thoughts

For women with coloured or damaged hair, using a keratin kit often feels like a risk. With the right kit and a bit of care, the result is different. Hair gets stronger, frizz eases, and styling each morning feels lighter. What matters most is simple: pick a trusted kit, apply it properly, and don’t skip the aftercare, even adding the Intense Moisture Pack when needed. Do that, and a keratin treatment kit isn’t just safe — it becomes a way to bring back smoothness and strength, even if the hair has gone through years of colour and heat.
