1 Lipid-soluble hormones (steroid hormones and hormones of the thyroid gland) diffuse through the cell membranes of target cells. 2  The lipid-soluble hormone then binds to a receptor protein that, in turn, activates a DNA segment that turns on specific genes.he thyroid hormone consists of two components, thyroxine and iodine. This hormone increases the metabolism of most body cells. A deficiency of iodine in the diet leads to the enlargement of the thyroid gland, known as a simple goiter.
This will get rid of the most brittle, dry hair. You may even like to get the ends trimmed once a month or every other month until your hair returns to its normal texture. In 6 to 12 months most of your chemo curls will be gone and you'll be free to try new styles with your short hair. Enjoy your new hair.
The reason doctors are sometimes vague about when cancer patients can expect hair to regrow is that it depends how long you're going to have chemotherapy and the spacing of the cycles. Think of it this way: each chemotherapy treatment, or cycle, kills the fast-growing cells in the hair follicles. So your hair is actually starting to regrow again after each chemo treatment, but you can't see it because the next treatment causes it to fall out again. Once you've had your last chemo treatment, you should start seeing regrowth within four to six weeks. But it will be slow; you can expect about a quarter inch of new growth each month. You may notice that your hair is a different color or texture when it regrows; most peoples' hair comes back in cury, at least at first.
