There are too many unhelpful replies to your question. When I asked many years ago for recommendations bald people came out of the word-work to try to shame me into just cutting it all off. Most of them get angry when I suggest they do them, and I'll do me. They need to validate their own choice to themselves or something. Anyways, I've had two good experiences at Apex in Thong Lo. It might be a little more expensive than the average here in Thailand but they had some famous thai personalities use their services in the past so I trusted them more. Quite happy with the results 4 years later.
