To help prevent BV from returning, there are many recommendations by Doctor Willacy.
Suggestions include not pushing water into the vagina (known as douching), and not adding bath oils, scented soaps, perfumed bubble baths, or shampoos to bath water.
It will also help to “not use strong detergents to wash your underwear” and to only wash around your vagina and vulva “once a day” using “gentle soaps and water”.
The use of perfumed “intimate hygiene” products should be ceased, and showers – rather than baths – are recommended.
