need help using homemade body and hair wash recipes

hello mums,
i am trying to avoid soaps, shampoo and creams for my girls 4 and 2 years old.
i mixed besan with milk and almond oil for my girls dry skin wash. and made besan milk only for hair wash. i also put tea tree oil drops to the mix for nice smell.
girls are not comfortable as they were used to bubble wash. but i managed to finish the whole thing. after their skin and hair were clean. but does smell strange.
can you please give me some recipes of homemade ubtan and natural hair wash for kids that also smell pleasant..please help me ..
i tried coconut oil as body and face moisturizer. but it did not make any difference to their dry skin. they have dry skin no eczema ...i tried almond oil . It worked lil better. i heard about olive oil as it make skin tan? is is true?
