Oily/Greasy hair

My hair is naturally greasy. I heard that it's just because I'm in my teen years.Is there a way to make it less greasy? Is there an ingredient I can put in my baking soda mixture.

thymealso between washings spray on and leave in a strong thyme teahow often u wash? washing too often promotes oiliness u strip oils so u produce more..washing weekly (slowly extend the time so it adjusts)is probly bestu can use thyme oil, but being an oil it will add to oilines till it adjusts so a tea maybe betteralso sea salt sprays should dry the hair ..but..over use of em can possibly trigger the scalps responce to increase oil production to compensate..(i think)

I started with 2 days and slowly worked to 4. I'm trying to get to 7.I'll try the Thyme.I think I might be spraying the sea salt spray too much. I use it right after I shower. Now I realize I spray it too much every time.

better to use it BEFORE you shower an hour or 2 before then wash it out Fiend Jester said:
