What goes on your hair does not stay on your hair.

What goes on hair and scalp, including the part most guides skip: a product chosen for your hair does not stay on your hair.

It runs down the hairline, sits along the temples, and spends the night on a pillowcase against your cheek. That is why a conditioner or an oil that suits your hair can be the thing breaking out your face, and why a routine assembled from hair advice and a routine assembled from skin advice can quietly disagree with each other on the same bottle.

So these posts read a product for both places at once, and then again for pregnancy, breastfeeding, postpartum, trying to conceive and PCOS. The answer for a scalp treatment and the answer for the skin underneath it are not always the same one, and the profile you have set is what decides which of the two you needed.
