Hair Cycle Expiration Date

I have a 2 year old bottle half used haircycle biotin spray from a previous hair transplant. I just got another hair transplant and I am wondering if it is still safe to use or has it expired?

Hair cycle biotin spray should be effective and safe to use for two years if kept in normal room conditions during that time. If you leave it in extreme cold or heat, then the life span will be less. In that your bottle is already 2 years old, you might want to buy a new bottle. You might consider the smaller travel size bottle since you used only 1/2 your bottle last time. With the biotin spray, you need to apply only a light mist. You do not need to soak your scalp such that it drips down your forehead. The latter is too heavy of an application.
