Frequently asked questions
If my hair is frizzy and dull, which line should I use?
The Strengthening line with Bio-Keratin, also known as Smooth and Silky. Bio-Keratin is developed from a special blend of amino acids obtained from wheat and soya. Those amino acids are complex protein structures that are immediately compatible with the proteins present in the hair follicle and the hair fibre. Hair needs protein because it is made of keratin, and it also needs collagen. Consistent use of Bio-Keratin improves and softens the hair fibre, giving hair that is easy to shape, shiny and free of frizz.
What is Bio-Keratin and what does it do for hair?
Amino acids are the building blocks of every protein in the body, and hair is made of a protein called keratin. If too few amino acids reach the cells in the hair follicles, keratin production drops or the keratin produced is defective, and the result is fragile hair. Bio-Keratin supplies three key amino acids: arginine, which the body stops synthesising well under stress and with age; lysine, which stimulates collagen and matters for repairing damaged hair; and methionine, an antioxidant that helps protect the follicles from oxidative stress. Its benefits: it strengthens the hair follicle and the hair fibre, stimulates growth, allows perfect styling and leaves a smooth finish.
Why should I avoid shampoo with sulfates?
Ammonium lauryl sulfate (ALS) and sodium lauryl sulfate (SLS) are abrasive detergents and one of the classic ingredients in almost every shampoo: they clean and degrease through the foam they produce. They are used because they are cheap and effective, but in a short time they wear down the scalp and the hair. In stripping the oil they also destroy the natural lipids the skin produces to defend itself, which makes them irritating. Many problems of dryness, scalp irritation and dandruff come from their continued use. The whole Nouvie hair line is sulfate free.
Why does the shampoo barely foam?
Because it is sulfate free, and sulfates are precisely the detergents that produce all that foam in conventional shampoos. The Strengthening Shampoo cleans with a gentle plant-derived agent: it is normal for it to barely foam on the first wash and to foam a little on the second. It cleans just the same, only without being harsh on the scalp.
Why is hydrolysed quinoa good for hair?
Hydrolysed quinoa is essential for a healthy nervous system and for the formation of red blood cells, which promotes hair growth. In the formula it also provides hydration and helps protect against dandruff, and alongside Bio-Keratin it prevents the strand from breaking.
Why are yogurt protein and prebiotics good for hair?
Protein from natural yogurt strengthens the hair fibre, reduces breakage and encourages healthy growth in the follicles. It provides vitamins B6 and B12, zinc that strengthens the scalp, lactic acid whose moisturising properties make it a great natural conditioner, and calcium and magnesium to nourish the follicles. Prebiotics favour the good bacteria on the scalp and inhibit the harmful ones, which helps to balance it, improves hair density and leaves hair strong, shiny and tangle-free.
How often is it used and how long does the kit last?
The shampoo is used at every wash, the mask 2 to 3 times a week left on for 5 minutes, and the styling lotion daily on damp hair, left in. At that frequency, the complete kit (237 ml shampoo, 177 ml mask and 177 ml lotion) lasts several weeks on medium-length hair.
Can each product be bought separately?
Yes. The shampoo, mask and styling lotion from the Strengthening line with Bio Keratin are sold individually, as well as in the complete 3-step kit. Message us on WhatsApp and we will confirm prices, availability and delivery.
Treatment Steps
Strengthening Shampoo
Wash your hair with the Shampoo using an amount of product suited to your hair's length and volume. Shake a little before use, massage the scalp in circular motions and rinse with plenty of room-temperature water. It is normal for it to produce no lather on the first wash; on the second it lathers only slightly because it is sulfate free and its formula uses a gentle plant-based cleansing agent.
Strengthening Mask
Apply the Mask immediately after the Shampoo. Remove excess water, shake a little before use and place a portion suited to your hair's length and volume in the palm of your hand, rubbing for a few seconds. Apply evenly from mid-lengths to ends, leave on for 5 minutes and rinse with plenty of water, preferably cold. Use 2 to 3 times a week.
Strengthening Molding Lotion
After washing your hair with Nouvie Shampoo and Mask, towel dry, shake a little before use and place a small portion in the centre of your hand according to your hair's length and volume. Rub between your hands for a few seconds and apply evenly all over the hair without rinsing. Then style as you like, letting it air dry or using a hairdryer, straightener or curling iron. Apply daily to dry hair to style and as protection against UV rays.
