I don't want to beat a dead horse but in some instances it's better to seek the aid of a professional than to save a few dollars and do it at home.

Although having a license doesn't make someone an expert in all arenas, it does increase the chance that you'll get the results you desire. 

A licensed professional has studied, does understand the nature of hair and chemicals.  In general, a licensed professional will know more than the average person and will be able to remedy problems when/if they arise.

If you're coloring mature Dreadlocks, have damaged hair, have already had a bad dye job or you're lightening your color, it's best to see
k professional advice because chances are, you will need some corrective work or it may be best to wait entirely before coloring your hair again.


Choosing a Colorist...
Have an in-salon consultation. Tell the colorist the results you desire and ask her/him to weigh the pros/cons of choosing that particular shade.

Inquire as to what type of colorant and brand she/he will be using and why. This will help you just in case you change colorists in the future but liked the results of the initial product.

No matter how you sport your 'do, the colorist should inquire about your hair history. If not, volunteer such information like the last time you relaxed, used henna, colored... If she seems uninterested...Be Out!

The colorist should then examine your scalp.

Any cuts or abrasions and she should advise you to wait before coloring.

If everything seems ok, she should do a patch test the day before your scheduled visit to insure that you won't have any allergic reactions to the product.
