Why am I attracting different people since I dyed my hair?

I used to have black hair, but I attracted men who wanted to date me (I met through dating apps). But men strangers will ignore me and wouldn't give me the time of the day. I recently dyed my hair dark brown, men strangers treat me nicer and also notice me and give me more attention. However, guys I go on date with (still using dating apps), seem to not want me anymore for relationship, only sex... why is that?
