How to protect and revitalize damaged hair

Article Navigation

Damaged hair is one of the most common problems I see daily in the salon and affects women and men of all ages. It doesn't "break" overnight; it's the result of habits that are repeated: excessive heat, wrong dyeing techniques, intense styling, aggressive products, even stress or poor nutrition. All these gradually weaken the hair, making it look dull, dry and lifeless. The good news? ✔️ It can recover. In this complete guide, I'll show you—with the knowledge of 25 years behind the barber's chair—how you can restore life, shine and strength to your hair, with practical steps that truly work.

1. Suitable Shampoos for Damaged Hair

The first and most important step to restore your damaged hair is choosing the right shampoo. Shampoo isn't just a cleansing product—it's the foundation of a healthy care routine. The wrong shampoo can dry out hair even more, "open" the hair cuticle and intensify frizz. The right one, on the other hand, can start the restoration process from the very first wash.

• For stressed or damaged hair, prefer shampoos with moisturizing and restorative ingredients. The most effective ones usually contain natural oils (like argan and coconut), proteins (like keratin or silk), aloe, panthenol and glycerin. These ingredients help retain moisture and restore elasticity and strength to the hair. Avoid shampoos with very strong cleansers like SLS and SLES, which can strip away the natural oils your hair needs to recover.

In the barbershop we see daily that the biggest "culprit" for damaged hair isn't always heat tools or dyes—but the wrong shampoo. Many clients use products that make hair "shine" instantly but weigh it down and dry it out over time. For example, with clients who have colored hair, we often observe that a sulfate shampoo fades the color 2 times faster compared to a sulfate-free one. Also, for hair with split ends, a protein shampoo can make a real difference in just 10 days.

• A "rule" we always say: If your hair feels rough in the shower, your shampoo is wrong. The right shampoo should leave hair softer and more elastic from the very first application, without weighing it down. If you don't feel this, change it.

Also, don't wash too frequently. 2–3 washes per week is ideal. Too frequent washing removes essential lipids, leading to dry hair and damage. For clients with very dry hair from dyes or frequent styling, we often recommend alternating between two shampoos: a moisturizing one and a restorative one with proteins. This balance helps the hair absorb nutrients without "hardening."

Finally, the water you wash with plays a bigger role than you think. Very hot water opens the outer layer of the hair shaft resulting in more damage, dryness and dullness. Prefer lukewarm or cool water, especially in the final rinse, to "seal" the hair cuticle and lock moisture in.

3. Apply Leave-Ins — The Hair Shield

Leave-in products are among the most underrated yet most important formulas for damaged hair. They work like an invisible shield that stays on the hair and protects it from the environment, styling, heat, humidity and daily friction. In the salon I always explain that a Leave-In isn't "just another product"—it's the base that keeps hair stable and hydrated throughout the day.

• For colored hair, leave-ins with UV filters are essential: they protect the color from fading and maintain the dye's intensity longer. If hair is fine and frizzes easily, I recommend light formulas with plant extracts, which offer moisture without weighing down the hair. If it's thick, damaged or very dry, then a richer leave-in with oils, proteins and keratin makes a difference in texture and shine.

The most common mistake I see with my clients is the wrong amount: they either put too much product, or so little it has no effect. The correct rule is a hazelnut size for fine hair and a walnut size for thick hair. Also, application is always on damp—not soaking wet—hair so it's better absorbed by the hair shaft.

• Another secret I recommend in the salon is using a wide-tooth comb for even distribution. The difference in results is impressive, especially when the leave-in is used daily. After 1–2 weeks, most clients report less frizz, better hair manageability and noticeably softer texture.

Leave-In is like a "daily treatment" that works in the background. When combined with the right mask, gentle shampoo and heat protection, it becomes a key pillar in the effort to restore hair to a healthy state. It's also ideal for people who avoid heavy product use, but want a result of softer hair, less breakage and more flexibility.

4. Get Professional Treatments — The Solution for Very Damaged Hair

There are cases where home care products aren't enough to save the hair. When hair is extremely weak, dehydrated, with split ends and loss of elasticity, then the solution is professional treatments at the salon. With higher concentration of active ingredients and more specialized techniques, these treatments target deep hair reconstruction.

• It's impressive how quickly the difference shows: many women notice an immediate change in softness, shine and hair feel within just one session. Keratin, amino acids and strengthening proteins work like foundations that rebuild the hair from within. In the salon, I always customize the treatment according to the level of damage, hair type and dyeing history.

A professional treatment isn't a luxury—it's an investment in hair health. Especially for those who've undergone consecutive bleaching or drastic techniques, a series of sessions can prevent breakage and gradually restore hair cohesion. In these cases, I always combine the treatment with systematic home care, so the result lasts for weeks.

• Often in the salon I see that women who choose professional treatment once a month have noticeably healthier hair than those who rely only on retail products. The difference lies in the concentration of active ingredients, but also in proper application. Heat placement, dwell time and chosen products play a crucial role.

If hair is very damaged, professional treatment isn't just an "extra step," but a necessary stage for the repair process to begin. And when combined with proper home care routine, then the return to healthy, glossy and flexible hair becomes reality.

What Those Who Tried the Treatments & Masks Say

5. Be Careful with Coloring — Reducing Damage & Maintaining Color

Hair coloring is one of the main reasons leading to damage. In every chemical process, the pH rises, the hair shaft opens and natural lipids are removed. The more frequently this happens, the weaker the hair becomes and the harder it is to recover. In the salon I often see women who dye their hair every 3-4 weeks at home, without proper protection, and the result is dry, porous and lifeless hair.

• That's why I explain to my clients that the right coloring strategy can prevent significant damage. First step: we always choose a shade close to natural. Intense color changes—especially very light ones—require continuous bleaching, which is one of the most aggressive factors for hair. In contrast, a close shade is easier to maintain and doesn't require constant repetitions.

Second step: we choose products specifically for colored hair. They're designed to "seal" the color, reduce fading and maintain shine. Using shampoo and conditioner for colored hair isn't a marketing "trick"—it's a real need, especially if coloring is frequent. Lukewarm or cool water in rinsing also reduces opening of the hair shaft and helps maintain the shade.

• Another basic mistake is intense styling immediately after coloring. Hair is more vulnerable at that moment and needs 1–2 days for the color to stabilize. If heat must be used, heat protection is mandatory. Also, I recommend clients avoid washing on the same day as coloring so pigments aren't removed.

For those with very damaged or excessively bleached hair, the solution isn't more coloring. It's strategy: spacing of 6–8 weeks, protection products, hydration masks and sometimes techniques like root melting, balayage or natural shadows to reduce the need for frequent renewal. This way, hair breathes, rests and gradually recovers.

6. Cut Split Ends — The Simplest and Most Essential Step

Split ends are one of the most common problems I see in the salon. They're insidious: if not cut in time, they "climb" upward, destroying greater hair length and creating a frizzy, dull result. That's why regular trimming isn't just about aesthetics—it's about hair health.

• In most cases, a small trim every 8–10 weeks is enough to keep ends healthy. When hair is already very damaged, I recommend more frequent appointments until the situation stabilizes. Trimming helps not only in removing damaged ends, but also in uniform hair growth.

Also, using the right products—leave-ins, masks, heat protectors—prevents the formation of new split ends. Hair that's hydrated and elastic doesn't break easily. In the salon I explain that hair doesn't break "randomly": it first loses its moisture and elasticity. When we strengthen these two, then breakage is noticeably reduced.

• With clients who want to grow their hair longer, I often hear "but I don't want to cut even an inch." But without trimming, the length they're keeping is essentially damaged and will be cut more later. The right approach is: little and often. This way they grow healthy and solid, without thinning at the ends.

Finally, for people with colored or frequently straightened hair, I recommend special home treatments that strengthen the hair tip and reduce damage. With a combination of right products and regular trimming, hair regains the elasticity, shine and movement it had.
