can you dye bohyme hair without ruining it? If I want to go darker would a home hit such as color spa loreal moisture actiff harm it??? The dye is semi permanet (24 washes) and doesnt contain amonia? I was told that the semi permanent color spa is actually good for your hair because its "adding moisure to your strands" (something like that), does this seem to make sense at all? any advice on this one... thanks :) **nikki**

I've had a few customers dye their hair darker with out any problems but I'm not sure what products they used...

As far as I know it's ok to "add" color to Bohyme and make them darker but I've heard unsucessful stories about people trying to get them lighter in color which ruined the hair...

When in doubt, try a test strip before you do the whole head

My advice would be for you to do a strand test first chick as I have colored bohyme hair a few times with mixed results.  I used loreal excellence (permanent color) which had a special serum with it which i put on the ends of the extensions before colored to protect them.  I felt it did affect the quality of the hair though, however only slightly when coloring darker and like straw with bleach. 

A semi-permanet color may have different results too.  We once colored indian remi hair in the salon with loreal dia color (semi permanent) and it ruined the extensions).

I dye my human hair darker all the time with no problems.  I use a demi-permanent, but a semi would be fine too.

Just do a strand test first.  Also, this hair is highly processed, so it can go dark quickly, you need to watch your timing.

Demi permanent has no ammonia and a very low level of peroxide (like 3-7 volume).  You mix the color with the developer. It is considered an oxidating color because the peroxide does allow for the color molecules to penetrate the hair to get inside the cortex.  But because the volume is so low, it really doesn't have any lifting power.

Semi permanent has no ammonia and you don't mix it with peroxide.  It is not an oxidating color, it's really just a direct dye that doesn't penetrate the hair, it just sits on the outside of the strand.  However if the hair is porous from being previously chemically treated, than the hair's cuticle is raised somewhat so this semi color could indeed 'seep' inside the hair, thus permanently staining the hair.  This is what many blonds find out the hard way when they use a semi to color their hair darker and think that because it's a semi, it will wash out.  They don't take into account their hair's porosity.
