Textured hair has special care and styling needs based on its unique curl patterns. Inspired by celebrity stylist Andre Walker's hair types and built upon by NaturallyCurly readers and hair professionals, our texture typing system details the varieties of wavy, curly and coily hair. We've put together handy charts to help you identify your hair type at a glance. We've also given you quick care and styling tips as well as product recommendations to help keep your waves, curls and coils looking their best everyday.
Hair disorders result in the production of defective hair fibers. These disorders damage the outer cuticle layer and may expose the inner cortex to various hair treatments like curling, relaxing, pressing or coloring. The exposure to these strong hair treatments weakens the overall strength of the hair fiber.
Gradual weakening of the hair fibers is involved in hair shaft defects and hair disorders like pili torti and monilethrix.
Pili torti(trichokinesis, corkscrew hair) is the general name for rigidly twisted hair. The twisting of the hair fiber occurs at focal points along its length. There may be several twists in one hair fiber.
In this hair shaft disorder the cuticle layer remains intact and is not stripped away as in Trichorrhexis nodosa. But the rigid twisting of the hair fiber through 180 degrees creates stress, which leads to fractures in the cuticle and internal cortex layer of the hair shaft.
Hair shaft disorders may lead to brittleness and uncombable hair. In general the hair feels dry and lusterless. Hair shaft abnormalities may occur as localized or generalized disorders. Genetic predisposition or exogenous factors are able to produce and maintain hair shaft abnormalities. In addition to an extensive history and physical examination the most important diagnostic examination to analyze a hair shaft problem is light microscopy. Therapy of hair shaft disorders should focus to the cause. In addition, minimizing traumatic influences to hair shafts, such as dry hair with an electric dryer, permanent waves and dyes is important. A short hair style is more suitable for such patients with hair shaft disorders.
In some people, the reason their hair moves is because there are alternative cellular energy pigments attached to their hair strands. New science has shown that some peoples bodies produce alternative cellular energy pigments as an immune system response in an attempt to stop the cell damaging effects of a virus. The pigments provide a non-mitochondria source of cellular energy. The alternative cellular energy pigment pathway is similar to photosynthesis in plants. Alternative cellular energy pigments are also known as ace pigments.
First I do provide moderation, not customer service. If you are dissatisfied, I could not care less. I aim to provide a safe, polite and spam free experience to all users of this forum.
Second, what you post on this forum do not belong to you, but to the owner of the forum (A group I do not belong to, by the way) and in a wider sense to the community of Biology-online. If you have exposed yourself to the world in a way that you do not like, well too bad. I would remove personal identification put by mistake, but not opinions that you are ashamed of, but do not care to disavow.
If you disagree, feel free to contact the admins, but in the meantime you are banned for your stupid spamlike posts.
Enjoy your day.
