Thanks for checking in and glad the ACV is working so well for you.
Similar to you I quit using all the hair wash products I used before. However, I haven’t completely got rid of shampoo.
Instead I’m just using a high quality extremely moisturising shampoo, it seems to have improved my overall scalp help and things balanced out. It took a while to wean off of dandruff shampoos thought. It seems like as you stop using them, the scalp isn’t sure what to do at first.
If you would like, share your complete approach and I can append it to the main post.
All the best.
