Dear Beauty Brains,
I know that fats in natural oils like coconut or olive can partially remove the artificial colour deposited to one’s hair through a hair dye or tint. This is why I never use natural oils or products containing high level of these on my hair, at least 2-3 weeks after colouring in a salon. However, I do use different conditioners and leave-ins that contain silicones, quats and polyquats to condition and mask hair damage. So am just wondering if they contribute to fast colour fading and wash-off the same way as fats in oils do. And which of them can really ruin the colour quickest? Another question is: are these special lines of shampoos and conditioners for colour-treated hair really more effective in making it last longer than regular lines (or again it’s just a marketing trick). And all those lines specially designed for blondes, like John Frieda… Do they keep the cool blonde colour in place longer that regular colour-saving lines, which cater all: brunettes, redheads, blondes etc.
HUGE thanks in advance for your enlightening answers!Color lines are really just a marketing gimmick. They have less detergent so they aren’t as stripping but you’re unlikely to see much difference between using a color product line versus a normal shampoo.
Lines for specific colors have some technologies that might help blonde specific people (violet #2) but there really isn’t anything that is special beyond that. There certainly isn’t something that is particularly good for brunettes or red-heads.
Silicones will not strip colors much. The thing that is most responsible for stripping color is getting the hair wet. It opens the fibers and color can slip out. If anything, silicones will help keep color in the hair better.
Thanks a lot, Perry!
So your take is, if you are a blone and want to keep it longer, it’s ok to stir to special blonde lines versus traditional ones. Otherwise, don’t bother.
The thing is, within the brands like John Frieda, there are several lines for blondes. And here is when it gets confusing to me. They, for example, have a line where violet color is deposited, as you mentioned.
And I totally see the rationale for buying these if you want to fight yellowness.
However, there’s also a line with no color deposited, which is primarily for keeping the blonde bright (whatever that means). Will this second line do any difference to make the dye stick to the hair longer?
Are there any researched ingredients or products that are proven to influence colour longevity at all?Here’s their ingredient list.
Aqua, Sodium Laureth Sulfate, Sodium Lauryl Sulfate, Cocamidopropyl Betaine, Sodium Chloride, Cocamide MEA, Parfum, Silicone Quaternium-18, Glycol Distearate, Benzyl Alcohol, Guar Hydroxypropyltrimonium Chloride, Trideceth-6, Disodium EDTA, Trideceth-12, Malic Acid, Glycine, Persea Gratissima, PPG-9, Helianthus Annuus, Stearoxypropyl Dimethylamine, C14-28 Isoalkyl Acid, Propylene Glycol, Sodium Hydroxide, Caramel, Pentylene Glycol, Lecithin, C14-28 Alkyl Acid, Methylchloroisothiazolinone, Stearyl Alcohol, Methylisothiazolinone, Alcohol, Camellia Sinensis, Tocopherol, Ascorbyl Palmitate.
There is nothing special in this formula that would help keep hair blonder longer (or brighter).
Oh such a dupe )))
So there are no researched ingredients or products that are proven to influence colour longevity, got it.Well, to be fair there are probably ingredients that raw material suppliers sell which they’ve demonstrated under lab conditions can make blonder hair last longer. I’m just saying there is nothing that you could use in a product that would make any noticeable difference.
