Q1: Why does my new Remy hair smell like rotten eggs?

A: That’s likely sulfur compounds from chemical processing. A vinegar soak usually removes it completely.

Q2: Can I use essential oils to mask the bad odor?

A: Not recommended. Oils can build up on wefts and trap bacteria, making odors worse over time.

Q3: How long does it take for the vinegar smell to disappear?

A: Vinegar evaporates quickly. After rinsing and air-drying (6–12 hours), no vinegar scent remains.

Q4: Will baking soda damage the hair cuticle?

A: No, when used as a paste for 10–15 minutes and rinsed with cold water, it’s safe and effective.

Q5: Can I wash extensions with regular shampoo to remove bad odor?

A: Shampoo alone rarely removes chemical residues. Use vinegar or baking soda first, then shampoo as normal.

Q6: Is it safe to use rubbing alcohol on colored extensions?

A: Use with caution. Test on a small weft first — alcohol can strip some dyes.

Q7: How can I tell if the bad odor is mold vs. chemicals?

A: Mold smells earthy, musty, or like wet cardboard. Chemical smells are sharp, metallic, or like ammonia.

Q8: My extensions still smell after 3 treatments — what now?

A: Return them. Persistent bad odor after multiple deodorizing attempts indicates irreversible contamination.
