Olaplex can be used as a stand-alone treatment to re-boot heat-damaged and coloured hair like mine, but it can also be used as part of the colouring process, which is its real selling point. The three-step programme works by repairing bonds within the hair shaft, known as disulphide bonds.
The urea and water are released from the liver cells to the bloodstream and transported to the kidneys where the blood is filtered and the urea is passed out of the body in the urine.Urea is very soluble and a small molecule, so it is relatively easily passed out by the kidneys as a solution in water.xcretion and the liver Excretion in mammals Excretion is the removal of potentially harmful or toxic substances from the body. These substances are usually waste materials produced by complex chemical reactions taking place in living cells. Enzymes catalyse the reactions.
When amino acids are burned as a fuel, ammonia (NH3] is the waste product. Ammonia must be carried to the liver, converted to urea and excreted by the kidneys. One of the penalties of amino acid excess is ammonia excess, a potential cause of body malfunction following a high protein meal. The blood measurement of urea nitrogen (BUN) shows the balance between urea production by the liver and excretion by the kidneys. The BUN rises in kidney failure and serves as a measure of ammonia or nitrogen. In liver disease, reduced ability to synthesize urea leads to ammonia accumulation.
