“Whatever you can do on Chol Hamoad you can do during Safiras HoOmer BH O’CH 493”
It’s not a one to one relationship. If it’s mutar to shave during Chol Hamoed, then the same circumstance would be mutar to shave during sefira. However, there’s a lot more room to be meikel with sefira than with Chol Hamoed. People get heterim to shave for work during sefirah, which they would not get during chol hamoed.
I thought Sphardim shaved during sefira? I know Rav Ovadia was matir shaving during the 3 weeks, so I might be confusing the two.
