Shelo Tisganah Al Ba'aloh

We find in Halacha 3 times the concept of Shelo Tisganoh Al Ba’aloh.

Chazal allowed one to be oiver an issur  d'rabanan, lest the wife becomes

repulsive to her husband.

a) On Yom Kippur one of the five inuyim is, not to wash oneself. The Mishna

(Yoma 73b) and Shulchan Aruch (O.Ch. 613- 10) say, Chazal made an

exception for a Kallah*1 the first 30 days after marriage. She may wash her

face on Yom Kippur Shelo Tisganoh Al Ba’aloh.

b) In Shulchan Aruch Hilchos Niddah (Y.D. 195 - 9) we find ," Bekoshi *2 Hitiru

Lekashet"- With great difficulty Chazal allowed women who are a Niddah,

to apply make up .The reason they allowed it, Shelo Tisganoh Al Ba'aloh.

c) Peiah Nochris (wig) or  Cobul (hair net) , are prohibited to be worn on

Shabbos in a Reshus Harabim. Chazal allowed women to wear them, in a

Chotzer (court yard) without an Eiruv, Shelo Tisganah Al Ba'aloh. (Shabbos 64b) .
