YOLU Relax Night Repair Shampoo (475ml) is a core product in the brand’s "Night Scalp Care Series", focusing on "scalp soothing and stress relief + intensive night repair". The 475ml large-capacity design meets both long-term personal use and family sharing needs. The packaging is mostly a pump bottle (or flip-top mouthpiece), which is convenient for controlling dosage and preventing liquid contamination.

The product’s core advantage lies in "adapting to the physiological characteristics of the scalp at night": the scalp is in a state of active metabolism and high repair needs at night. This shampoo adopts a dual-effect formula of "low-irritation cleansing + high-active repair" — the cleansing end uses amino acid surfactants (gently cleanses scalp oil and dirt, avoiding over-cleansing that damages the barrier); the repair end adds chamomile extract (soothes scalp redness and itching, relieves daytime stress), panthenol (vitamin B5, hydrates the scalp and improves dry tightness), hydrolyzed keratin (penetrates hair strands, fills cuticle damage, and reduces frizz), and is also combined with vitamin E (antioxidant, reducing free radical damage to the scalp and hair strands).

The texture is transparent or light milky white liquid, which produces fine and rich foam (no false slippery feeling) after rubbing with water. It has a light scent (no artificial fragrance added, mostly natural plant fragrance). After rinsing, the scalp is fresh and not tight, and the hair strands are soft and shiny; its pH value is close to the scalp’s weak acidity (about 5.5-6.0), adapting to the natural acid-base environment of the scalp. Long-term use can enhance the scalp barrier function, improve scalp sensitivity and dry hair problems, and is especially suitable for night hair washing scenarios.

Core cleansing and repair ingredients:
Amino acid surfactant (Potassium Cocoyl Glycinate): A mild cleansing surfactant with fine foam, which can remove scalp oil and dirt, while avoiding damage to the scalp’s natural sebum membrane, reducing tightness after cleansing, and adapting to the need for gentle cleansing at night;
Matricaria Recutita (Chamomile) Extract: Contains flavonoid active substances, soothes scalp redness and itching, reduces scalp irritation from daytime sun exposure and pollution, and aligns with the "Relax" soothing positioning;
Panthenol (Vitamin B5): Penetrates the scalp to replenish moisture, improves dry tightness of the scalp, and penetrates hair strands to enhance the moisture retention capacity of hair and reduce frizz;
Hydrolyzed Keratin: Small-molecule protein that can penetrate into the gaps of hair cuticles, fill damaged areas, enhance hair toughness, and improve dryness and breakage after perming/dyeing;
Vitamin E (Tocopheryl Acetate): An antioxidant that scavenges free radicals produced by the metabolism of the scalp and hair strands at night, reduces oxidative damage, and delays scalp aging and hair fragility.
Mild base and stabilizers:
Solvents: Purified water (gentle and non-irritating, used as an ingredient carrier to ensure uniform dispersion of active ingredients), Glycerin (assists in moisturizing, avoiding excessive moisture loss from the scalp and hair strands during cleansing);
Foam booster: Cocamidopropyl Betaine (compounded with amino acid surfactants to improve foam richness and stability, while enhancing gentleness and avoiding scalp irritation);
Stabilizer: Disodium EDTA (prevents reactions between ingredients and metal ions, avoids product stratification and discoloration, and maintains long-term stability of the 475ml large-capacity product).
Safety guarantee ingredients:
Preservative: Phenoxyethanol (a mild preservative that meets international hair care product safety standards, effectively inhibits microbial growth, ensures the usage cycle of the large-capacity product, and prevents deterioration);
No additives: Free of alcohol, artificial fragrances, artificial colors, sulfates (SLS/SLES), and irritating preservatives, reducing the risk of scalp irritation at night, and suitable for sensitive scalps, barrier-damaged scalps, and dry hair.
(Note: The specific ingredients are subject to the labeling on the product packaging. Slight adjustments may be made in different production batches due to raw material supply, but the core cleansing and repair ingredients remain consistent.)

Basic night hair washing steps:
① Moisturize the scalp and hair strands: First, thoroughly moisten the scalp and hair with warm water (32-38℃, close to body temperature, avoid overheating to irritate the scalp), ensuring the hair roots are fully wetted (facilitating subsequent cleansing and foaming);
② Take and lather: Take an appropriate amount of shampoo (about 1 pump for short hair, 2-3 pumps for medium-length hair, and more for long hair as appropriate) in the palm of your hand, add a small amount of warm water and rub until fine foam is produced (it is recommended to rub for 10-15 seconds to ensure uniform foam);
③ Gently cleanse the scalp: Apply the foam evenly on the scalp and hair strands, and gently massage the scalp with your finger pads (avoid scratching with nails to prevent damage to the scalp barrier) in a "circular" motion (focus on cleaning areas with excessive scalp oil secretion, such as the top of the head and hairline). Control the massage time within 1-2 minutes (avoid over-massage causing scalp irritation);
④ Rinse thoroughly: Rinse the foam on the scalp and hair strands thoroughly with warm water (ensure no residue, as residue can easily cause scalp itching and increased dandruff). After rinsing, you can match it with the same series of conditioner as needed (especially for dry hair, focus on caring for the ends of the hair).
Enhanced usage for sensitive scalps:
If the scalp is obviously sensitive and red, reduce the amount of shampoo (1/3 less than usual) and shorten the massage time (control within 1 minute). Rinse the scalp slowly with running water when rinsing, avoid rubbing the hair strands vigorously, and reduce irritation to the scalp.
Precautions:
Avoid contact with eyes (if it accidentally gets into the eyes, rinse immediately with plenty of water); it is recommended to use it at night (to meet repair needs), once a day or every other day (adjust according to scalp oil secretion; dry sensitive scalps are recommended to use every other day); store away from direct sunlight and place in a cool and dry place.
