when you heat the hair up it becomes more damaged and split ends become more visable
The retention of solar heat is just one effect...
Heat is transferred by conduction in a flat iron through direct contact between the hot heating plates and the hair strands. The heat is transferred from the plates to the hair through the molecules of the material, producing a straightening effect by breaking down hydrogen bonds in the hair.
Heat is not strictly necessary to lighten hair with lemons, but it can enhance the process. The natural acidity in lemon juice, combined with sunlight or heat, can help activate the lightening effect more effectively. If you're using lemon juice without heat, it may take longer to see results, and the lightening effect might be less pronounced. Always follow up with conditioner, as lemon juice can be drying to the hair.
A surface conditioner effects the hair's cuticle and, to make it penetrate even deeper into the cuticle, an outside heat source is often used.
the curly hair absorbs the direct radiation of the sun; and protects the skull. due to the curly hair, the skull get heated only by conduction; and thus is subjected to less heat. the effect is like that of wearing a cap
You shouldn't use ANY heat on a doll's hair. The hair is attached with plastic and using heat will melt it causing the hair to come out.
The heat sort of "sets" your hair in the shape your curlers make it
How heat affects the hair when conditioning
good effect: keeps hair in place bad effect: chemicals that are in it
Burn it (Burn your hair)
Hair deals mainly with heat. The brain is particularly sensitive to heat. Hair on the skin can trap air to keep heat in, or keep perspiration near the skin to take heat as it evaporates. The groin and armpits are heat sinks.
The heat is obviously generated by the the electricity which is provided by the socket. The the heat from the electricity conducts through the hair straightener resulting in the hair straightener to straighten your hair
