Did pregnancy change anyone’s curl pattern? I had very tight kinky curls before I got pregnant now they are more loose and wavy. My hair hasn’t really gotten longer (as I cut it every 8 weeks) so it not added weight...I’m using the same products. I do get my hair flat ironed by my stylist but that’s only every 8 weeks too and it’s never changed my pattern before. I like it just curious
