L'oreal Professionnel Source Essentielle Nourishing Oil 70ml

Hair oil treatments are used to nourish, hydrate, and strengthen the hair. They penetrate the hair shaft, helping reduce breakage, increase elasticity, and boost natural shine. Oils are rich in essential fatty acids and vitamins that help repair damaged cuticles and protect against environmental stress, heat tools, and chemical processing.

Depending on the formula, oil treatments can be used before shampoo (pre-wash), after towel drying, or even as an overnight deep-conditioning ritual. They're especially helpful for taming frizz, sealing split ends, and restoring softness to dry or dull hair.

Oil treatments can work for nearly every hair type — but are especially beneficial for dry, curly, frizzy, and damaged hair. These textures tend to lack moisture and are more prone to breakage, so nourishing oils help rebuild softness and flexibility.

If you have fine or oily hair, it’s best to use lightweight oils like argan or grapeseed, and focus the application from mid-lengths to ends. Avoid putting oil directly on the scalp if it tends to get greasy, and instead use it as a leave-in or rinse-out treatment.

For best results, warm a small amount of oil between your palms and apply it evenly from mid-lengths to ends. Avoid the scalp if your hair is oily. Leave it on for at least 20–30 minutes before washing, or use it overnight for deeper nourishment.

You can also use a few drops as a leave-in treatment after towel drying to control frizz and add shine. For curly or thick hair, apply more generously to define texture and reduce dryness.

Yes, hair oils are excellent for color-treated or chemically processed hair. They help lock in moisture, reduce breakage, and protect the hair fiber. Natural oils like argan, coconut, and macadamia are rich in antioxidants that preserve color vibrancy and restore softness.

Use oils that are specifically labeled as color-safe, and avoid mineral oils or those with harsh silicones. Apply from mid-length to ends for best results.

How often you use hair oil depends on your hair type and condition. For dry or damaged hair, 2–3 times per week can provide deep hydration and repair. Oily or fine hair may only need it once a week to avoid buildup.

Regular use helps restore the hair’s natural balance, especially if you use heat tools or color treatments. Listen to your hair’s needs and adjust accordingly. You can always start with once a week and increase as needed.

Look for natural oils such as argan, jojoba, coconut, and castor oil — all known for their deep moisturizing and repairing properties. Additional ingredients like vitamin E, keratin, and botanical extracts boost nourishment and add shine.

Avoid mineral oils and synthetic fragrances that can weigh down or irritate the scalp. Cold-pressed and organic formulations are generally more effective and gentler on the hair and scalp.
