My hair has been bleached for years now, and the struggle to keep the cuticles down (aka make it look shiny) is hard

In reply to Michelle. Thanks for your reply. I am elated. So, hypothetically, if the color covers 100% of the hair shaft, there is no gap, does that mean the hair shaft will remain dry ? I am imagining that the color is like a raincoat, instead of wearing a cotton clothes.

In reply to Noni. There are still lots of gaps in the hair for water to get through - water is tiny!

Hi Michelle,
I know that this is an old post and hopefully You can shed some light to this as I struggle to find an answer to it.
After coloring the hair with semi-permanent color (you know those the like of manic panic / arctic fox), does water penetrate the hair shaft? Because the color “coats” the hair.
Thank you very much.

Thanks for telling me that using semi-permanent dye on my hair means that it can fade after a few washes. I only need to color my hair dark for a formal event, but I’m really in love with my natural blonde hair. It might be a good idea to look up salons in our area and see if they offer this service.

Hi Linda! Try using shampoo and conditioners for curly hair that contains AMODIMETHICONE(https://labmuffin.com/amodimethicone-my-new-favourite-hair-ingredient/). Another thing you can do is making a hair mask with vinegar or lemon. The acid will close the cuticles and make the hair smoother.

In reply to Jill.

I don’t know too much about hair dye ingredients – I do know that para-phenylenediamine (PPD) causes really bad reactions, but that’s about it. I’m always a bit skeptical about hormone disruption claims, especially since they recently found that soy xenoestrogens might help prevent cancer by being weakly estrogenic and blocking stronger estrogens from binding. But again, I haven’t done much research on it yet!

Thank you so much! ^_^ I am actually working on something, though not on hair science…

This is a really clear explanation. Thanks. I’m really interested in using the least harmful permanent dye, by that I mean gentle to my hair and my body. I read that the synthetic coloring agents can cause allergies, cancer, hormone disruption and what not. But even the ‘natural’ brands use them! I’m really curious what you think, since you are not the type to get scared easily lol. Also, as far as hair health there is some discussion whether ammonia alternatives are actually gentler.

I could go on, I want to know so much haha. For example if Wella Innosense really prevents allergic reactions, what you think of color removers like B4., why natural pigments can’t be brought into the hair, why there are no other less harmful pigments than the typical ones. By the way if you wrote a book I would totally buy it. ^^
