Anything with high chemicals. Alcohol is a huge one that's in a LOT of hair products that really damages your hair after a long period of uses. But you can shop around and find product Alcohol free so yeah hope this helps :) Heat also damages hair. Straighting irons, curling irons, and blow dryers. But you can find shampoos and conditioners that can repair and prevent damage. :)
Sun or humidity or both
A bit more:
Over processing hair can cause a great deal of damage. If you color, perm, or relax your hair, any of those can result in damage. With each of these procedures, you need to wait at least seven days in between before another process.
Consult your hair stylist for a trim, or even a full cut, to get rid of the damaged hair, then use a good shampoo and conditioner made specifically for damaged hair.
A couple other ways hair gets damaged is by applying an excess amount of heat (blow drying, curling, straightening, etc.), using too many hair products, and lack of care.
Hair dye from the grocery store is damaging in a way that the minerals and "dyes" you get in a box color are harsh on your hair's natural structure.
The color at a salon is less damaging by far, but it really depends on what you're looking to do. "Permanent" hair color at the salon uses a "developer" to help the color take to your hair. That's where the real damage is. If a person wants to go lighter, the percentage of hydrogen peroxide in the developer is higher, and more damaging. If you're staying the same color or going darker it's less. If you're in the United States and have no gray hair, be sure your stylist is using a "10%" developer, many of them reach right for the "20%" but it's not necessary if you don't have grey hair or if you're not going lighter.
So, to sum it up and paraphrase, it's not the color that's doing it, it's the amount of peroxide in the developer that you need to be wary of. Anything more than 20% is going to damage your hair more than you'd probably like, so talk to your stylist before making any dramatic changes and you should be fine :D
The cream dye mixture makes the hair shaft swell to accept the color and process further. Certain ingredients that do this are metallic lead and bismuth citrate --- and in proscribed doses that are approved as safe. Our hair has keratin and it's the sulfur within that oxidizes with the chemicals, causing a color change.
it causes hair fall.
Well if you curl or straighten your hair after a while it will start to get heat damage and if you go to get it cut they will have to cut the damaged parts cut off my friend had to cut hers really short because she straitened it every day.
It's the peroxide that is mixed with the color that damages hair. Especially when going lighter, because a higher volume of peroxide is used.
They don't.
If your hair is tangly all the time, then the friction of hair rubbing together can in fact damage the surrounding hair.
