Is it normal?

nothing out of the ordinary but is it normal for my hormones to affect my husband while I'm pregnant? Before I got pregnant he had to constantly cut his hair because a week after cuting it he looked like a monkey, lol. But right now I'm 5 1/2 months pregnant and he cut his hair for the first time since I found out I was pregnant. He cut it in January and it's now almost march and it still looks like it's only been about 3 days since he we got it cut. 🤔
