I don't know how the beta would figure in to this equation since it represents the movement of the stock relative to an index like the S&P; 500.

I understand the risk free rate of return for which I use the one year Treasury Bill as my benchmark (presently 0.25%) However, I don't understand what you mean by the Market offering a premium of 8%? Do you mean a stock that pays a dividend of 8% over the T-Bill rate? I guess I need more information from you to answer the question. Sorry. - Ray Seakan

Lash extensions can last any where from 3 weeks to six months if taken care of properly. To keep them looking good and make them last you need to make sure you aren't rubbing your eyes or sleeping on your face and crushing them.

Also, avoiding soaps, lotions and makeup removers with oil in them will keep them lasting. You will also want to get regular fills for the hairs that will fall our with your natural hair growth cycle.
