Baking soda wash with no oils

So for the baking soda wash, it seems like everyone adds oils. People say these oils are cheap...I don't know where you guys live, but here it's not.So I was wondering...could I just do water and baking soda and an acv wash if needed?Thanks!P.S. I bought some "Naturelle Hemp Hydrating Shampoo" today. Would this work? It doesn't say non-residue or anti-residue and does have chemicals in it. The only anti-residue I could find was Neutrogena but I heard bad things.

hydrating is conditioning good if yoir black bad if not

the oils are cheap becaujse 1 bottle lasts months and months

i just spent like 50 on oils but when they last 6 to 8 months thats cheap (that was like 6 or 7 oils and shipping)

the baking soda can be used withoit the oils ofcourse the oils are strictly medicinal if u dont have a medicinal need u dont need oils

tho teatree is also preventative so is lavender

the rest are to treat conditions only

if u just get teatree 5 dollars worth will last 6 months

I just use the baking soda wash with out any oils. I have tea tree oil, but it is missing at the moment, and I never added it to my wash any way. So you are in the clear! Works for me!

Well it looks like I don't have much choice. I'd rather get dandruff than mold from residue.Thanks for the quick replies.

Ive never used oils man and im closing in on my 2 years long mark
