Guanidine hydroxide relaxers are a little easier to stabilize from a product development standpoint, and can be effectively used for up to two years.
This is characteristic of relaxers in this category, which contain calcium hydroxide. At best, a product that is beyond its shelf life will not perform as effectively as it did initially.
Product application may be impaired and the way it reacts to the hair may very well be hindered. At worst, the product could cause harm to a client.
In the case of an unstable or separated sodium hydroxide relaxer, the result will either be ineffective straightening or extreme causticity. This is because once a relaxer separates, the oils rise to the top and the water, containing most of the sodium hydroxide, descends to the bottom of the jar. When the stylist applies the upper portion of the mixture, the hair will be treated with the most impotent part of the relaxer.
Relaxers are supposed to be able to last for quit some time, but as soulchild said, try the sniff-check. If it smells really strong, or if the color is a bit off, don't use it. Personally, if it's been sitting for over a year, I would toss it. Ayeshia New Member. But then when it expires it smells like fish or something i hate that smell. I have heard up to 2 years. But I agree with Pebbles.
Allandra Well-Known Member. Yeah, I'd probably just do a sniff test as well. I have had and used old relaxers. If you think that it is old don't use it unless you want a texturizer because it won't take.
I purchased a tub of mizani from someone on this forum about a year ago Since you don't know how long it was on the shelf before you purchased it, I would see if it passes the sniff test and of course, do a strand test to see if it takes. No-lye relaxers reportedly are ineffective beyond 24 hours of being mixed. Hi Ladies, I learned the hard way what an outdated relaxer can due to your hair!
I lost most of my hair years ago when I purchased a relaxer at a BBS store- I thought I was getting such a good deal bc it was on sale. When I went to rinse it out along went most ofmy hair down the drain!! I learned that you can phone the company, most provide an on the container, or phone 's version of for any Once you reach the company, you can ask what the code is that they use to identify the date of expiration.
When you learn that then you never have to guess again. You'll be able to pick up any product from their line and tell the expiration and manufacture date- while still in the store, before you buy it. These codes are designed to be cryptic which I think is stupid. They are usually lightly printed in purple ink on the outside or bottom of the container.
