Mild Side Effects Serious Risks
Allergic reactions Allergic reactions such as asthma
Itching Irregular breathing
Skin irritation Irregularity in heart rhythm

These side effects may seem rare to you. However, studies point out that these effects may be seen depending on the amount of ammonium chloride taken in the body.

Here, the frequency you use fibers, how much you apply, whether there is a different source of ammonium chloride in the foods you consume are effective. Besides, individual sensitivity is extremely important.

Do Hair Fibers Affect Hair Growth Negatively?

No! The hair fibers are too large to block and fit in the follicles. Thus, they can’t have any adverse effect on growth. Besides, the high-quality fibers do not settle on the scalp and instead adhere to the hair strands one by one and perform their functions.

Fibers neither adversely affect hair growth nor do they encourage it. They do not have a positive or negative effect here. They are only used to hide the sparse areas and to make the relevant area look more intense.

Thickening fibers produced from cotton have higher adhesion ability. Because of this, they adhere better and gather much less on the scalp.

Do Hair Fibers Leave Stain Where They Contact?

A significant portion of the tested keratin brands caused staining of the fabrics despite being washed. The main reason for this is the low colorfastness. In other words, the durability of colors against external factors is not at a sufficient level. As far as the scalp is concerned, it has been found that the fibers cause coloration of the scalp when in contact with moisture. In cotton fibers, on the other hand, these problems are less common.

Staining, which is among the side effects of hair fibers, is not valid for every brand. These problems in the products of reliable and well-known brands are rare. However, before purchasing the relevant products, it would be useful to ask the seller for information on staining.
