Each four studies had obtained step by step details regarding hair dye use, including dates and duration of use, and NHL sub type. The pooled analysis contained 4,461 women with NHL and also 5,799 females who did not have NHL.

Although these outcomes are consistent with the notion that previous hair dyes were far significantly more carcinogenic, it is also possible that the lack of increased hazards for hair dye users that began utilizing dyes after 1980 reflects lower accumulative vulnerability levels or insufficient time because first vulnerability for any increase in risk to develop into clear.
