A cellophane, a color gloss, a rinse and a semi-permanent are all the same thing - for the most part. Where it begins to get tricky is brands.
They are different than some semiperms in that they contain no peroxide. There are no damaging ingredients at all. The Nick Chavez would qualify - but if it needs to be mixed - beware. It's harsher than it lets on. Not HARSH necessarily mind you - but harsher than it claims to be.
If you use any color that is closer or lighter than your natural color, it will wash out gradually over the course of a few shampoos. 10? 20? - Depends on your hair, the kind of shampoo you use and a host of other factors, but the bottom line is they are designed to wash out.
I apply mine all over each time about every 4 weeks. I either use clear or a color that compliments the shade I'm wearing at the time. When I go dark, I consider it a permanent change since the porosity of my hair from previus permanent color jobs have caused my hair to soak up color and not let go. If your hair is overprocessed in ANY way expect the color to be permanent. I mention this because often people use black rinses thinking they'll just wash out and when they don't...
I only apply monthly with the brands I KNOW don't have peroxide in them tho - Sebastian, Adore, Jazzing etc....
If it contains peroxide you should only touch up the roots, but if it's not a permanent color, you can reapply it if you missed a spot without much of a problem unless you hair is ultra sensitive.
True rinses - those without peroxide - help keep the cuticle smoothed down so they help avoid routine manual damage, and they give the hair a brilliant shine and an overall healthy appearance. The usually carry a very low PH - 3-4 - and usually contain silicone and /or protein - so if your hair is sensitive to those be careful...
Overall - they are unlikely to cause a problem and can assist in your hair growth journey by helping to protect the hair and help it to look as healthy as possible.
The rule of thumb for telling the difference is often experiential:
1. Semi-perms generally, don't require peroxide. The one exception is Bigen - they get away with calling themselves a semi-perm because they have somehow put the peroxide in the powder - and all you have to do is mix with water. Add that to people like Cathy Howse SAYING it doesn't contain peroxide and the confusion is bound to occur. Sebastian, jazzing, Adore, Rejuvatone etc. all fit into this category.
2. Colors that need to be mixed with developer, and call themselves semi-permanents are really DEMI-permanents. The confusion comes in because manufacturers of these products often CALL them semi-permanents and the haircare industry has taken the ball and ran with it (no dount to target folks who are looking o color, but are looking for buzz words that indicate less damaging - like 'semi-permanent'. They use a mild peroxide formula (10-20 volume) to push color further into the cortex so they last longer. Sometimes I use this in place of permanent color when I don't want to go lighter, because they can be permanent. L'oreal Casting, Natural Instincts and Bigen fit into this category.
If you prefer this category and neat trick is to take the bottle of developer you get in the kit and dump out anywhere from 1/4 to a 1/3 of it. Replace what you've discarded with water and conditioner - or either. What you end up with is a milder more conditioning formula, the peroxide has been diluted to a lower concentration and the color comes out the same because it's not meant to lighten anyway - so you get enough color deposi using this method to get good color, less some of the damage.
3. Permanent color is also mixed with developer but it's stronger - usually a 30 volume. This is the "bad stuff".
HTH!
u are a doll! Ill just call u the color queen from now on!
