Input (English): [header] How to prevent hair color from bleeding [title] Use conditioner to keep color dyes from bleeding onto lighter hair. [step] During the dyeing process, coat lighter hair in conditioner to protect it. The conditioner will act as a shield when you rinse the dye itself out, lessening the unwanted contact that the dye has with your hair. <sep> (A) [substeps] Make sure the conditioner is water-proof for water dyes, as water can increase dye absorption into your hair. Do not use " water-proof " conditioner as this can affect color oxidation, and water can halt dye absorption. (B) [title] Wait 24 hours before shampooing your hair after getting it dyed. [step] Washing it too early can dislodge the coloring agents. (C) [title] Apply a heat protectant product to ensure your hair does not get too dry. [step] The most effective, but sometimes needed, heat protectant formulations are laser hair straighteners, which shrink hair with a low heat setting. (D) [title] Always apply conditioner to your dyed hair immediately. [step] Doing so will promote the color to fade, lessening the time it needs to remain in your hair.
