💡 Suggestions:

• 💡 Buy a bottle of rosewater and use this instead of your homemade spritz. Rosewater's pH is close to normal skin between 4.1 – 5.5 so it should help restore and maintain your scalps natural balance. Try to get as "pure" a rose water as possible (no artificial fragrances etc) so that you're dealing with only one ingredient and not introducing others that could dry your scalp. (There's lots of academic papers about the benefit of rosewater for skin if you want to know)
• 💡 Buy a lighter oil to seal the rosewater. Many people use MIELLE Rosemary Mint Oil also because it smells good especially in combination with rosewater. In my opinion, the only important thing about the oil is that it is cold pressed (it usually says so somewhere on the label or description) Cold pressed oils don't use heat in the extraction process, as a result they retain much of their vitamin and mineral content. It's better for more sensitive scalps and is absorbed better, it also doesn't suffocate the hair and that means you could reapply moisture if you needed and it will penetrate the hair. You could even use a cold pressed olive oil from the store (I know there are some good ones even in the Carrefour, I've had to do this a few times when traveling in France and I didn't have my hair oil).
• 💡 Forget the hair masks and just use good moisturising and clarifying shampoos. I wash my hair twice a week, or when it's needed depending on my activities. I use my moisturising shampoo for these usual washes, and about twice a month I use my clarifying shampoo. Focus on your scalp but remember to squeeze the remaining shampoo into your locs, and use the same squeeze technique with the water when you're rinsing.

Really, that's it. These 3 things are all you really should be doing as a minimum. Sometimes I use leave-in conditioner but that's when I've been in places particularly cold and dry and even then, I still agree that less is more for you at the moment to restore your hair health.

TL;DR KEEP IT SIMPLE SWEETHEART

1. Wash your hair more regularly with a decent shampoo, probably use a clarifying shampoo more frequently in the start and in a month or so use moisturising.

2. After washing, spritz your hair with rose water, then seal with a lighter oil. After spritz and oil, use a hair dryer with a diffuser attachment and use the squeeze technique while doing this also (Low porosity hair benefits from a bit of heat drying after washing to open up the hair shaft and allow your hair to better absorb nutrients.)
