Rate It: Do You Influence Your Partner's Beauty Buys?

Perusing himselfs bathroom cabinet the other day, I was struck by his products - skincare by Shiseido, Vichy and Biotherm, haircare by Aveda and Redken and fragrance by Tom Ford and Chanel. I like all those brands myself, and I may have made a few suggestions - and purchases too. It made me wonder - how much do we influence the purchases of our other halves?

Do you reckon you have a lot of influence over what products your partner buys, or do they resist all advice and doggedly stick to their old favourites? And do you buy products for them too?
