Formulated with botanically inspired ingredients, the product aims to give even gray coverage for a short-term color change that lasts through multiple washes.

Conditioning agents help the pigment bind evenly to hair fibers, so most users see visible darkening in a single 15–20 minute treatment. Results are immediate after rinsing, with full tone developing once hair dries.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReady-to-use shampoo—no mixing, bowl, or brush required\u003c\/li\u003e\n  \u003cli\u003eActive pigment and conditioning compounds for even coverage\u003c\/li\u003e\n  \u003cli\u003e15–20 minute application time for a quick at-home service\u003c\/li\u003e\n  \u003cli\u003eSuitable for straight, curly, fine, and thick hair textures\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat level of gray coverage and longevity can I expect?\u003c\/h3\u003e\n\u003cp\u003eCOSMTEK’s dark brown formula is designed to cover white and gray strands effectively for a semi-permanent result.

COSMTEK Dark Brown Hair Dye Shampoo is for adults—women and men—seeking a fast, low-effort way to mask gray hair and revive a natural dark brown color without a salon appointment. It's a good match for people with varying hair types (straight, wavy, curly, thick, or fine) who prefer a semi-permanent touch-up rather than a long-term chemical dye. If you want a quick at-home solution to refresh color, reduce visible gray, and maintain softness with conditioning agents, this product can fit into your regular hair-care routine. Remember to perform a skin sensitivity test before first use and follow the instructions for best results.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long does each application take?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Apply the shampoo, massage through wet hair, wait 15–20 minutes, then rinse for immediate color.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this shampoo damage my hair?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It’s a semi-permanent conditioning shampoo formulated to be gentle; perform a patch test first to check for sensitivity.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"COSMTEK","offers":[{"title":"Default Title","offer_id":51485610213609,"sku":"B0B424M8M2","price":68.27,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/7674\/2633\/files\/cosmtek-pack-front-dark-brown-shampoo.jpg?v=1783194201","url":"https:\/\/cervaaustralia.com\/products\/cosmtek-dark-brown-hair-dye-shampoo-17-6-fl-oz-semi-permanent-gray-coverage-in-15-20-min-conditioning-3-in-1","provider":"Cerva Australia | Professional Beauty Supplies, Skincare \u0026 Cosmetics","version":"1.0","type":"link"}
