I can think of three reasons:
1. They prefer the look of straight hair or slightly wavy hair. They may be natural for reasons like hair health, not anything deep/political.
2. They think straighter hair (weaves) are easier to care for, which they can be.
OR
3. It's just easier to find/buy relaxed-texture hair...again, not that deep.
The first two reasons are the same reasons why I relax my hair. I don't like weaves, but I like how straight hair looks and I find it easier to care for. That's why whenever my friends who transitioned with or protective style with straight weaves preach to me about relaxers, they get the side-eye. My sister transitioned with wigs and she washed, detangled, and braided her hair once a week, so she was still learning how to take care of it. Actually, she already knew how to care for natural hair because my niece is still natural.
