Sounds like a great hobby. Do you intend on selling the products you make?I’ve never used a shaving soap on my head. What do you use a brush and straight razor? I’ve used a straight razor once and it was a blood bath.
My neighbor and his wife are into all kinds of handicraft copies, Such as working with stain glass and creating useful objects etc..His wife has been making homemade soap for as long as they been married she makes very many different types and adds different essential oils and natural scents to them. The soap Keeps forever and the longer they store them the harder the bars become.It is a bit of a process so she only does it about once a year.
That sounds like some great stuff you got going, Buddha
I just use some conditioner on my scalp. Seems to work great althogh it doens' have to cooling or the scent effect but at lease i get to press down hard and no nicks. Whatever works , works.
