I'm 27, on keto for 3 months and besides the diet, my skincare also became so minimalistic which I absolutely love.
Because of my poor diet in the past, I had flakey dry skin and rosacea on my very pale and sensitive face. So I decided to do some changes.
For 3 months I use tallow balm which I make by myself from rendered suet fat and some extra virgin Greek olive oil. It recovered my extremely dry and sensitive skin on face, lips, body and using it as a deodorant too. Both dietary changes and all natural skincare had tremendous benefits inside out. So, I'm sticking to it.
For hair I use 1 egg yolk as a shampoo and an ACV/water mix as a rinse. Works wonders as a weekly hairwash routine. That's it.. simple, cheap and effective stuff is what I love.
