Answer:
Heat opens up the cuticle, much the same way ammonia does chemically. This way some dyes will suggest covering your head or applying heat while the color sets. The extra heat, whether from your own head or an external source like a blow dryer or steamer, optimizes the dye's processing for stronger results.
Explanation:
- The cortex is the main body of the hair shaft - it contains natural moisture and color pigment, which is the translucent cuticle.
- The outer layer of the hair shaft, its cuticle, must be opened before permanent color can be deposited into the hair. Once the cuticle is open, the dye reacts with the inner portion of the hair, the cortex, to deposit or remove the color.
Because they are high in fiber and complex carbohydrates, whole grains do not break down as rapidly as refined grains in the digestive tract, and so they do not raise the blood sugar as dramatically,
Cerebrospinal fluid (CSF), clear, colourless liquid that fills and surrounds the brain and the spinal cord and provides a mechanical barrier against shock. Formed primarily in the ventricles of the brain, the cerebrospinal fluid supports the brain and provides lubrication between surrounding bones and the brain and spinal cord. When an individual suffers a head injury, the fluid acts as a cushion, dulling the force by distributing its impact. The fluid helps to maintain pressure within the cranium at a constant level.
