Hi Sammiejane,
This is probably more detail than you need, but anyway here's my routine. Firstly I squeeze my sachet of Sandrena (1mg) onto the front of my mid thigh and spread that around using the middle finger of my left hand. Then I partially depress the Tostran pump so it dispenses the petit pots size blob onto the tip of my ring finger of my left hand, which gets rubbed slightly into the skin at the side of my kneecap, sometimes inner, sometimes outer. If I accidentally dispense too much I don't apply it all & just wipe the excess off my finger with a bit of tissue.
Wash hands and all done. Finish getting dressed about 15mins later.
Hair is possibly a bit better than before I was on this regime, but it's difficult to say as my hair is very fine. Eyebrows and lashes have certainly improved, but that wasn't difficult as they were very poor.
HTH,
S
