How to Hydrate & Moisturise Hair

Is your hair thirsty for some much-needed hydration? Dry hair not only looks dull and lacklustre but can be more susceptible to damage. Ahead, discover how to hydrate hair to achieve healthy, shiny locks.

How to moisturise hair depending on hair type

Dry hair is not only lacklustre but also incredibly susceptible to damage. Not taking care of your dry hair can cause it to fray and become brittle over time, which can then affect your comfort and confidence.

Now that you know how to hydrate hair, discover how to moisturise hair, manage split ends and restore health for any hair type.

Hydration for fine or straight hair

Harsh weather and heat styling can take their toll on fine or straight hair. When looking at how to hydrate hair that’s straight or fine, look at lightweight products that are infused with protein. Our hair naturally contains protein, which means protein-loaded products are highly effective at replenishing and adding body to the hair.

Be particularly mindful when applying conditioner, making sure to only apply it to the very ends of your hair to prevent it from weighing down your hair or making it appear oily. Our Nutritive range contains wheat and royal jelly proteins, nourishing each strand of hair from within. The end result is intense hydration that leaves hair feeling silky soft and lightweight.

Hydration for curly or wavy hair

Textured hair has a stronger hair cuticle, which means it requires more intense hydration. Don’t shy away from rich shampoos, conditioners and hair masks, and take care to only wash your hair once or twice a week so you don’t strip your natural oils.

Protective hairstyles can also minimise the risk of breakage and environmental damage. Try applying a conditioning product and then styling your hair into braids or twists to keep it safe. and all you did was pick up your smartphone!​

Adopting nourishing formulas and care habits is just part of how to hydrate hair, rediscover impeccable locks by learning the causes of dry hair and how to fix it.

Hair Hydration Tips

Knowing how to moisturise and hydrate dry hair involves using the right hair care products and developing healthy hair habits. To achieve and maintain hair hydration, read our top tips.

1.Protect your hair from the weather

Like skin, weather can effect the look and feel of hair. In terms of how to hydrate hair, one of the best strategies is taking steps to protect your strands from sun exposure, cold, and wind. Sun damage can lead to dry hair, so in summer apply UV hair protection to help maintain healthy looking locks. In winter, avoid going outside with wet hair as this puts your hair at risk of breakage. If you wear a hat, beanie or scarf, avoid coarse fabrics like wool and cotton. Instead, line your headwear with silk or satin to minimise breakage and split ends. This is particularly the case for curly hair, which can be more brittle and dry.

2.Apply hair masks regularly

Hair masks can help breathe life into your hair, particularly its ends. Your ends are the oldest part of your hair and therefore suffer from the most dryness. Our Nutritive Masquintense Riche Hair Mask is excellent at moisturising dry hair by nourishing hair fibres at the core. You can even take your hair mask treatment to the next level by applying it under a shower cap or plastic wrap – this creates heat that will further open up the hair cuticle and allow the product to penetrate deeper. If an at-home hair mask isn't enough, consider using an in-salon treatment like our signature Fusio-Dose In-Salon treatment.

3.Limit your use of heat styling tools

It’s no secret that heat styling tools can dry out the hair and may lead to heat damage. If you tend to style your hair with heat tools, always use a hair heat protectant to protect hair from any damage. The Nutritive Nectar Thermique Blow Dry Cream is a hydrating anti-frizz blow dry cream that will provide essential moisture while protecting hair from heat. Aside from minimising your use of heat styling tools in general, you can also use the ‘cool’ function of your blow dryer at the end of your styling session to seal your hair. This offers shine, locks in the conditioning agents you've used, and closes the hair cuticle.

4.Switch to hydrating products

One of the easiest and most effective ways to hydrate hair is through adopting specially formulated hair products for dry hair. The Kérastase Nutritive collection uses ultra-hydrating ingredients like niacinamide to moisturise hair and turn dry locks into a hydrated, healthy looking mane. Enhance hair hydration by implementing a care routine using shampoo for dry hair like the Nutritive Bain Satin Shampoo, and hydrating conditioner like the Nutritive Lait Vital Conditioner, alongside other hydrating hair treatments.

In terms of how to moisturise dry hair, a healthy growth environment is also key, so using a scalp serum like the Nutritive Scalp Food Hydrating Scalp Serum is an effective solution. This powerful vitamin serum helps to regulate and protect the scalp to support lasting hydration from root to tip.

5.Skip wash days

Too many of us have become accustomed to the idea that our hair needs daily washing. In reality, this can strip the hair of its natural oils and overload it with product. Instead, try to leave a few days between washes. If you feel like you still need some sort of hair cleanse, skip the shampoo and just rinse your hair with water, maybe applying some conditioner to your ends to infuse it with extra hydration.

6.See a professional for colour treatments

Any hair that endures chemical processing will experience some damage and dryness. While at-home colouring may be convenient, it can also increase the risk of damage and dryness. One of the best ways to maintain hair hydration is to leave colour treatments to the professionals. Colourists use salon-grade products formulated to avoid unnecessary damage and keep hair looking hydrated and moisturised.

7. Look for hydrating hair care ingredients

In terms of how to moisturise dry hair, care products enriched with highly nourishing ingredients are essential. The Nutritive collection includes expertly designed, ultra-hydrating formulas with ingredients like niacinamide, glycerin, and plant-based proteins that can boost overall hair health. Discover our hair care ingredient glossary to learn about each ingredient and how they can benefit your mane.

8. Use Hair Serum & Oil Treatments

Hair serums and hair oils are formulated to target dryness and increase hair hydration, in turn improving shine, gloss, and bounce. An effective addition to care regime for hair hydration, these treatments can be applied on damp or dry strands to aid with styling or enhance moisture overnight. The Nutritive Fibre Food Hair Serum is a nourishing dry hair serum designed to moisturise and replenish hair ends when used as a leave-in treatment after washing your mane. For additional nourishment, address dry strands through the long hours of sleep by applying 8H Magic Night Hair Serum before bed to reveal moisturised hair in the AM.

9. Receive regular trims

Dry hair often goes hand in hand with split ends so regular trims are vital to prevent further damage as split ends rise up the hair shaft. Visit a hairdresser for a trim every 6-8 weeks to help maintain a hydrated, healthy looking mane free of frizz.

10.Avoid rinsing with hot water

Washing hair with water that's too hot can lead to hair concerns such as a dry scalp, frizzy texture, dryness, and breakage. This is because hot water can make hair more porous, drying out strands, prompting breakage and brittleness. To maintain hair hydration, rinse shampoo and conditioner using lukewarm or cold water.
