No, you should never use a hot comb on wet hair.
Why Using a Hot Comb on Wet Hair is Harmful
Using a hot comb (or any high-heat styling tool like a flat iron) on wet hair is extremely damaging. Wet hair is significantly more vulnerable to heat damage than dry hair. The water inside the hair shaft turns to steam when exposed to high heat, causing the hair to literally explode from the inside. This leads to:
- Significant breakage: The steam expands the hair shaft, weakening its structure and causing breakage.
- Split ends: Heat damage makes the hair ends prone to splitting and fraying.
- Frizz and dryness: The intense heat strips the hair of its natural moisture, resulting in dryness and frizz.
- Irreversible damage: Extreme heat damage can permanently alter the hair's structure, making it difficult to repair.
Several sources confirm this crucial point: One source explicitly states that using a hot brush (similar in function to a hot comb) on wet hair should be avoided because it's like using a flat iron, and you should never use a flat iron on wet hair.

Alan Truman Blog While some products claim suitability for both wet and dry hair, this should be viewed with caution, and prioritizing dry hair is the safest practice.
While some sources mention using a comb on wet hair (referring to wide-tooth combs for detangling), this is completely separate from using a hot comb, which involves high heat.
Therefore, always ensure your hair is completely dry before using a hot comb to prevent damage.
