nerroneous at best.
I'm going to go one step further and offer some additional words of caution.Thank you all for the good advice.
Yes, but I thought everybody found scritchy wool irritable
As suggested by @nsavage in very small quantities with someone around.
Thanks @Monsta_AU will investigate options.
Back of your hand (which I previously suggested) is a good option but bear in mind that the skin there may not be as sensitive (the exact reason why it is a good starting point). This does not mean however that you will not have a reaction on your face. After a successful test on the back of your hand I would suggest behind your ear. This is a little more risky but is also considered a relatively safe spot. That may not ultimately mean that having lanolin exposed to skin that has been damaged by the act of shaving will not be an irritant.
The ultimate way to find out would be a prick test as suggested by @Monsta_AU.
I do have to say I am interested that you do not have a reaction with Stirling soaps. They use lanolin and they use fragrance oils.
