You see, people with thinning hair or even very fine hair, sometimes that hair is just not genetically anchored into the scalp as well, hence you can easily get root pull which may lead to permanent baldness from any bit of tension.

 

If your hair is thinning, there may be NO extension method that will not cause you further damage.

 

I am definitely a person whose hair is not able to support any type of extension anymore.  So, for myself I wear clip in wefts, that I custom made myself.  If my hair continues to thin, I will start wearing a lace front wig.

 

So, I'm giving you the advice that I give to any of my clients with really fragile hair: clip in extensions or a lace wig.  Perhaps you could get away with doing strands installed with micro rings too, it just depends on how much tension your hair can withstand.

 

Just stay away from glue and tape methods.   It will rip you hair out.

 

I have been doing extensions for 18 years and my clientele is largely caucasian.  There are many type of extension hair available that is quite suitable for caucasian hair types.  Most Indian hair is fine enough in diameter to work very well.  If you want to invest more money, you could opt for Russian hair too.
