• What is the Kérastase Nutritive Nutri-supplement Scalp Serum designed for?

  The Kérastase Nutritive Nutri-supplement Scalp Serum is a daily professional leave-in treatment and advanced hydrating scalp fluid engineered to deeply condition and hydrate dry, tight skin at the base of the hair. It functions as an essential vitamin treatment for dry scalp structures, delivering vital nutrients to alleviate tight discomfort and maintain scalp health without creating oily roots.

• How should I use Kérastase Nutritive Nutri-supplement Scalp Serum in my daily routine?

  Use this formula once every single day, either first thing in the morning or right before bed. Apply Kérastase Nutritive Nutri-supplement Scalp Serum section by section directly onto a dry or damp scalp, using your fingers to massage the liquid gently into the skin surface for a couple of minutes. Do not rinse it out after application; consistency is highly recommended for best effects.

• Will Kérastase Nutritive Nutri-supplement Scalp Serum make my clean hair look greasy or flat?

  Not at all. This watery clear gel hybrid is carefully engineered to dry down completely invisible within moments. Users have reported that Kérastase Nutritive Nutri-supplement Scalp Serum leaves absolutely zero sticky film, tackiness, or oily residue behind, ensuring fine or limp hair roots maintain their airy lift, natural movement, and fresh body all day long.

• What active ingredients drive the deep scalp hydration benefits?

  The formula relies on an intensive blend of plant-based proteins derived from wheat, corn, and soy complexes to feed the skin essential nutrients, combined with deep-conditioning Niacinamide to lock in moisture and support a healthy, strong, and flexible protective skin barrier.

• Is Kérastase Nutritive Nutri-supplement Scalp Serum suitable for all hair types?

  Yes, Kérastase Nutritive Nutri-supplement Scalp Serum is designed to be beneficial for all hair types and textures, particularly those experiencing localized dryness, flaking, or scalp skin discomfort. It promotes incredibly soft hair without weighing it down.

• Is Kérastase Nutritive Nutri-supplement Scalp Serum safe for colour-treated or bleached hair?

  Yes, this formula is entirely safe for colour-treated, highlighted, and heavily bleached hair structures. It focuses its active conditioning properties directly on the scalp's skin tissue, ensuring your roots remain soft and comforted without shifting or stripping away your salon colour.

• What is the exact size of the Kérastase Nutritive Nutri-supplement Scalp Serum bottle?

  The standard full-sized retail bottle contains 90ml of this premium leave-in treatment. The glass packaging features a precise dropper design that allows you to direct the fluid precisely across your different scalp lines without spilling or wasting any product.

• How many pipettes of the formula should I apply for each daily dose?

  The recommended standard amount is one to two full pipettes daily, filled right up to the top. Part your hair down the center and sides, apply the drops directly along those exposed skin sections, and massage thoroughly to evenly distribute the nutrient-rich fluid across your scalp.

• Will Kérastase Nutritive Nutri-supplement Scalp Serum help treat medical skin conditions like psoriasis or severe eczema?

  Please note that this product is a cosmetic conditioning treatment designed to relieve everyday dryness, dehydration, and tight skin discomfort. It is not a medical cure for chronic skin conditions like psoriasis or eczema. If you have severe scaling or inflammation, consult a medical professional.

• Can I use Kérastase Nutritive Nutri-supplement Scalp Serum alongside leave-in styling creams or blow-dry protectants?

  Yes, absolutely. Once you massage the liquid fluid into your scalp skin completely, wait a couple of minutes for it to dry down. After it has absorbed, you can safely apply your regular blow-dry milks, anti-frizz creams, or styling protective sprays through your mid-lengths as normal.

• How quickly will I notice an improvement in my scalp dryness?

  Most users experience an immediate sense of cooling relief and comforted skin elasticity straight after their very first application. Within a week of consistent daily use, localized tightness and flaking caused by skin dehydration are significantly minimized.

• What fragrance profile does this moisturizing scalp serum carry?

  It features the celebrated Nutritive aroma, a premium, upscale powdery fragrance. Kérastase Nutritive Nutri-supplement Scalp Serum blends top notes of citrus blossoms with a soft heart of blooming iris and a warm, comforting woody base, leaving a luxurious salon-fresh scent trailing behind your roots all day long.
