Review: Excellent, non greasy, nourishing hair serum - I absolutely adore this product and wouldn't be without it. It comes in a stylish, quality glass bottle. I use the product on my waist length, naturally wavy hair. It works well to nourish my hair and tame frizz. I know it's an overnight treatment but I use it as and when I need it. It doesn't feel greasy at all and seems to soak right in creating a smooth and hydrated feel to my hair. I've been using this product for a while and I think it helps prevent breakage and promote hair growth and strength. It smells amazing too which is always a bonus. If you're looking for a hair product that will nourish your long locks, without being greasy and that smells divine then this is the product for you. Yes, it is expensive but you don't need loads and it seems to last a long while. I think it's worth every penny to keep my locks in tip top condition. It took me a fair while to grow my hair long and this product helps to keep it strong and stay long.
Review: Wake Up to Transformed Hair! An Absolute Must-Have for Dry Locks! - If you have dry, dull, or frizzy hair, stop what you're doing and try the Kérastase Nutritive 8H Magic Night Serum – it's truly a game-changer! I've been using it for a few weeks now, and I'm genuinely blown away by the results. The idea of an overnight leave-in treatment for hair was intriguing, and this serum delivers on every single promise. I apply a few pumps to my mid-lengths and ends before bed, and the first thing I noticed is how lightweight and non-greasy it is. There's no residue on my pillow, and my hair doesn't feel weighed down at all. But the real magic happens overnight. I wake up to hair that feels incredibly soft, smooth, and deeply nourished. My dry ends are visibly healthier, and my hair looks shinier and far less frizzy. It truly feels like my hair has had a full 8 hours of restorative sleep! The inclusion of Niacinamide seems to be working wonders for improving overall hair health. It also has a lovely, subtle scent that's very pleasant. While Kérastase is a premium brand, a little goes a long way, making this bottle last. If you're looking for an effective, luxurious, and easy way to combat dry hair and wake up with gorgeous, manageable locks, this 8H Magic Night Serum is an absolute essential. Highly, highly recommend!

## Questions & Answers

**Q: How do I know if my hair is dry?**
A: Dry hair has raised scales and feels rough to the touch. Hairs are porous, dull and feel crunchy. The main cause of this is a lack of sebum, which naturally moisturises the scalp.

**Q: What are the benefits of the ingredients in the Nutritive range?**
A: Nutritive hair products contain a vitamin complex, plant-based proteins and Niacinamide to provide dry to very dry hair with essential nutrients and give hair more strength, softness and shine.

**Q: What's the best Nutritive routine for fine, dry hair?**
A: For fine dry hair, we recommend following Bain Satin shampoo with Lait Vital conditioner and Lotion Thermique Sublimatrice blow-dry mist. Then, to nourish dry ends with no greasy finish, apply 5 drops of the Split Ends Serum.

**Q: What Nutritive routine do you recommend for thick dry hair?**
A: For thick dry hair, follow Bain Satin Riche shampoo with the Masquintense Riche hair mask. To protect your hair before styling, finish your routine with Nectar Thermique blow-dry milk.

**Q: I have a dry scalp, which product would help me?**
A: The Nutri-Supplement Scalp Serum has been designed to hydrate all scalp types, providing a feeling of comfort from the 1st application. Its non-greasy formula preserves the scalp's protective barrier.
