1. Effective Waterproofing: Made of high-quality PEVA (polyethylene vinyl acetate) or EVA material—both are lightweight, flexible, and have strong water resistance, preventing water from seeping into the cap and wetting hair.
2. Comfortable Fit: The edge of the cap is equipped with an elastic band (usually latex-free to avoid allergies) that stretches to fit most head circumferences (54-58cm, suitable for adults and teenagers). The elastic is durable and not easy to loosen after repeated use.
3. Practical Design: The cap has a roomy interior, allowing it to accommodate medium-length to long hair without compressing the scalp. The transparent or semi-transparent version (common in the series) lets users check the hair coverage easily.
4. Hygienic & Reusable: The smooth surface of the material is easy to clean—simply rinse with water and air-dry after use. It can be reused dozens of times (depending on maintenance), making it more eco-friendly than disposable shower caps.

Main Waterproof Material: PEVA (Polyethylene Vinyl Acetate) or EVA (Ethylene Vinyl Acetate)—both are non-toxic, odorless, and compliant with international safety standards (e.g., FDA, EU REACH). They are free of PVC (polyvinyl chloride) and phthalates (plasticizers), which are potentially harmful.
Elastic Band Material: Latex-free Elastic (usually made of polyester or spandex blend)—avoids allergic reactions caused by natural latex, suitable for sensitive skin users. The elastic is coated with a thin layer of PE (polyethylene) to enhance water resistance and durability.
Additional Components (for Botanical Series):
Print Pigments: Water-based, non-toxic inks (used for floral/leaf prints)—free of heavy metals (lead, mercury) and harmful solvents, safe for contact with skin.
Fragrance (if applicable): Mild botanical fragrance (e.g., lavender, chamomile extract)—compliant with cosmetic-grade fragrance standards, low irritation, and fades naturally over time without leaving residue.

Prep Before Use: Ensure hair is dry (or slightly damp, if using to protect styled hair). Brush hair gently to avoid tangles—this helps the cap fit smoothly.
Put on the Cap: Hold the shower cap with both hands, stretch the elastic edge slightly. Place the cap over the top of the head first, then pull the elastic edge down to cover the hairline (including the forehead hairline and the hair around the ears). Ensure all hair is tucked inside the cap—no strands are exposed.
Adjust for Fit: Gently adjust the elastic edge to ensure it fits snugly around the head (not too tight to avoid discomfort, nor too loose to prevent water seepage). If you have long hair, you can tie it into a low bun first to reduce bulk and make the cap fit better.
Post-Use Care: After showering, remove the cap by pulling the elastic edge upward (avoid pulling hair). Rinse the inside and outside of the cap with clean water to remove any soap residue or moisture. Hang the cap in a well-ventilated place to air-dry completely before storing—do not fold it while damp (to prevent mold growth).
Maintenance Tip: Avoid contact with sharp objects (e.g., nail clippers, hairpins) to prevent tearing the material. If the elastic loses elasticity or the material is damaged, replace the cap in time.
