Answer
Thank you for your interest in a hydrogen peroxide-free grey hair cover shampoo formula in brown and black colors, manufacturing instructions, and ingredient ratios for a 20 kg batch, as well as guidance for new customers. Our current tools allow us to search for ingredients and existing products, but they do not provide specific manufacturing formulas with detailed instructions or ingredient ratios for custom batch sizes like 20 kg. This type of information, along with guidance on the ordering process for new customers, is best handled by our customer service team. Please contact the shop directly through their official contact channels (phone, email, website contact form) to inquire about available formulas or kits, technical support for scaling and instructions, and assistance with placing your first order.
