Postpartum hairless and dying hair

Kc🧜🏼‍♀️ • mj7/23/19🦋🦄

I’m 4 months postpartum. I’m considering getting my hair cut this weekend and I’d like to get some blonde put into my hair. And possibly layers bc my hair looks so thin.

My question is: should I do wait til this postpartum hair loss period is over? When is it over? I wouldn’t say I’m losing hair, mine just seems thinner.
