Protein Intensive Shampoo 400 ml with Aloe Vera, Argan and Keratin, Treated or Brittle Hair (Hair Care)

Chemically treated hair—dyed, highlighted, or straightened—requires a different type of care than virgin hair, and Atomy's Protein Intensive Shampoo is formulated precisely for this more demanding, breakage-prone hair profile.

Its formula combines aloe vera, argan oil, silk proteins, collagen, and keratin: a set of ingredients designed to strengthen weakened hair fiber, provide hydration, and restore some of the resistance that chemical processes often diminish in hair over time.

Each of these ingredients plays a distinct role within the formula. Aloe vera is known in cosmetics for its ability to provide immediate surface hydration, which is especially useful for a scalp that can become dry after repeated chemical processes. Argan oil, highly valued in hair cosmetics for its fatty acid and vitamin E content, is traditionally used to add shine and softness to the touch, especially in rough or frizzy hair. Silk proteins have a molecular structure that adheres well to damaged hair fiber, helping to temporarily smooth the hair cuticle and reduce that characteristic rough feeling of processed hair. Collagen, for its part, provides a slightly firming effect on the fiber, while keratin—the same structural protein that naturally makes up hair—helps fill the gaps left by chemical processes in the hair cuticle.

One of the most common mistakes with colored or bleached hair is continuing to use a shampoo designed for virgin hair, which often cleanses excessively and strips away some of the hydration that processed hair needs to avoid becoming brittle. A shampoo specifically formulated for treated hair, like this one, aims to cleanse with the same effectiveness but without that added drying effect, something that is especially noticeable in the hair's texture after several consecutive washes.

It's also worth understanding why colored or bleached hair behaves differently from virgin hair: the coloring process opens the hair cuticle for the pigment to penetrate the fiber, and this opening doesn't always close completely after the process, which leaves the hair more porous and more prone to losing moisture and hydration throughout the day. A shampoo formulated for this type of hair specifically seeks to compensate for this extra porosity, providing ingredients that help seal the cuticle instead of leaving it open after each wash.

I recommend it if you have dyed, highlighted, or straightened/permed hair, if you notice your hair is brittle or has split ends, or if you are looking for an intensive treatment shampoo beyond basic daily cleansing. It is also a good option if you frequently use heat tools such as straighteners or hairdryers, as this type of hair routine tends to weaken the fiber similarly to a chemical process, even if it doesn't involve coloring or bleaching.

If your hair is not dyed or processed and is fine, this intensive shampoo may be too nourishing for your hair type, leaving a heavy feeling at the roots; in that case, a lighter daily use shampoo usually works better, reserving these concentrated formulas for truly damaged hair or hair with recent chemical processes. Washing frequency also influences the result: washing colored hair too often accelerates color and hydration loss, so spacing out washes and using a specific shampoo for treated hair, like this one, helps maintain both color and general fiber health for longer between each color application.

Apply to wet hair, massaging the scalp and distributing to the ends, and rinse with plenty of water. You can combine it with the Repairing Treatment from the same Protein Intensive line for a more complete effect, using the shampoo with each wash and the treatment once or twice a week as an additional, more concentrated step.

One detail that many people overlook when choosing shampoo for processed hair is the water temperature during washing: very hot water further opens the already more porous hair cuticle in dyed hair, promoting the escape of the hydration that the shampoo has just provided. Finishing the wash with lukewarm or even cold water in the final rinse helps close the cuticle and allows the formula's ingredients, such as keratin and collagen, to remain better in the fiber until the next wash—a simple gesture that, combined with a shampoo formulated for this type of hair, makes a noticeable difference in the final result. This same gesture of rinsing with lukewarm or cold water, so easy to incorporate into any shower routine, is one of the recommendations I repeat most often to those who ask me how to extend the duration of color between salon visits.

If you are looking for a repairing shampoo for chemically treated hair, a formula with keratin and silk proteins, or simply an intensive shampoo for brittle hair, this product is exactly the type of product you are looking for: designed from the outset for processed hair, not a generic shampoo with a "repairing" label added without real changes in the formula.

I'm Kristina Farkas, an Atomy distributor—the Korean wellness and cosmetics brand with worldwide shipping—and this shampoo is one of the most requested among those who frequently color their hair or use heat tools daily. I ship it throughout Spain and Europe, managing each order personally and answering any questions about which hair line best suits your hair type before you place your order.

This shampoo combines very well with the Protein Intensive Repairing Treatment from my catalog for a complete repairing routine: the shampoo as a daily base and the treatment as a more intense weekly boost.
