Red Clover interaction with birth control?

I’ve been using Monat hair products for over a year now. I haven’t had any of the scary side effects that everyone has been talking about but I did decide to look into the products. I found a lot of people were talking about the red clover in it and it’s potential effects. I read that red clover can make your birth control less effective? My question is has anyone heard this from their doctor or experienced this? Does it make a difference if it’s in hair products vs ingested?
