Relaxers come in a range of brands, strengths and consistencies, but how do they work?
Instead of using heat to straighten the hair, chemicals are used to loosen the tightly set curls. Hydrogen and disulphide bonds are a main factor in determining the curl pattern of the hair.
Hydrogen bonds are bonds that form between water molecules, and are responsible for hair curling as it dries. When hair is wet, the hydrogen bonds are broken. As it dries, the what is a chemical relaxer for the hair reform, as do the curls. This is why hair can be manipulated by using rollers as a temporary alternative to relaxers. As the hair dries around the rollers, it holds its new shape once they are removed.
Disulfide bonds are much stronger than hydrogen bonds. These bonds form between sulfur atoms in hair fibres in order to provide strength in addition to the formation of curls. These bonds cannot be broken by water like hydrogen bonds, so hair relaxers are used. The chemicals present in hair relaxers break the disulfide bonds. This permanently straightens the hair. However, breaking these bonds makes the hair more susceptible to breakage and split ends. Illustration of disulphide bonds in hair fibres breaking due to the use of hair relaxer.

In chemistry, pH is a numeric scale used to state how acidic or basic a substance is. If it has a low pH, it is more acidic and if the pH is high, telaxer is more basic.
Hair relaxers are basic, with their pH ranging from 9 to 14 to ensure that they are strong enough to change the hair structure. There are different types of hair relaxers available of varying forr and made up what is a chemical relaxer for the hair different chemicals. Thio short for ammonium thioglycolate relaxers are much thicker in consistency than other relaxers, which makes them easier to apply. They have a pH value of at least 10 to ensure that enough of the disulfide bonds have broken.
The relaxer is then rinsed out and a neutraliser used to bring the hair back to its original pH value of 4. However, lye relaxers work in a slightly different way.
Teh this process, lye is the active ingredient. Lye is a mixture of sodium hydroxidewater, petroleum jelly, mineral oil and emulsifiers. The curls are then loosened as the hair fibre swells open. However, the amount of lye in the relaxer can vary, so weaker products can minimise the extent of damage to the scalp. Lye relaxers typically have a pH between 12 and 14 and do not require a special neutralising step, unlike thiol relaxers. Increasing awareness of the potentially harmful effects of sodium hydroxide led to the development of no-lye relaxers.
They work in the same way as lye relaxers, but the sodium hydroxide was replaced with potassium, what vitamins does your body need daily or guanidine hydroxides. This means no-lye relaxers are gentler on the scalp.
Once the hair is relaxed, it halr permanently straightened. But as the hair continues to grow, the roots will be natural. This means the relaxing process should be repeated regularly to achieve a consistent look, but excessive use of relaxers relaxdr cause damage over time, leading to chemical burns and hair loss. Relaxers contain strong chemicals to ensure that all the bonds holding the curls are altered. These chemicals can be harmful if overused or applied incorrectly.
