Need your opinions...........

Some of what I’m gonna say is going to come off harsh, and if it does I apologize now..

I am failing to understand why you are continuing to patronize a stylist who is not providing good service or even good work based on your description.. REGARDLESS of if she's the ONLY stylist you know of doing Tressallure extensions, you're CLEARLY not happy with her work.. Take your time and find a stylist who is going to make you happy.. Like Tangles said, don't be in a hurry or desperate..

Aside from the fact that until now you thought she was the only game in town, why are you even dealing with her?? There is NO WAY I would continue to pay this stylist one more dime or let her work on my hair if I'm not happy or if she is doing things I don't like!! However, if this were me, I also would have SPOKEN UP a long time ago.. This is YOUR hair and YOUR money.. You should have said SOMETHING to this woman long ago.. She's cut your hair when you didn't want it.. She's improperly installed the hair.. She doesn’t even wash the extension hair when she re-installs it, AND if she is using LESS hair on a re-install she is not following the Tressallure processes for reinstalls..(http://www.tressallure.com/movies/Movie_installation.wmv) and if you don’t mind sharing, what are you paying currently for this method, and what does the possible future stylist plan to charge?? Given the method, IMO this should be a fairly inexpensive installation.. Certainly not thousands of dollars.

So you found a possible new stylist.. Do you have to tell your (hopefully) soon to be former stylist that you are going to take your business elsewhere?? IMO.. NO you don't HAVE to talk to her.. You can talk to her if you would like her to know for her own professional growth, and hopefully she will improve for her future clients.. But if it were me, I would be done with her. You're not talking about one mishap, we're talking about and ON GOING mishap each time you see this woman.. IMO, that requires finding another professional to handle your needs..

Now, I understand the DIYers here advice to you, but I am one of those people who doesn't have the time (or the inclination) to put in my own extensions. I know it's easy to do, yada yada yada.. And there is no doubt in my mind that the DIYers here do AMAZING work on their own hair.. I am impressed, but I am saying that I can understand the desire to let a professional do this for you.. (the lazy factor) That said, you need to check out this other stylist out BEFORE you make the leap. Speak to the one client she has done. Ask if you can SEE her hair.. and when I say see her hair, I mean SEE HER HAIR.. Look at the bonds/wefts, see how the hair is placed so you can compare it to your own.. Should she give you a discount because she's NEW?? Absolutely!!! She SHOULD give you a discount if she's new at this, but a discount for her services, not the hair.. You need to AT LEAST pay for the cost of the hair (without a markup).. She shouldn't eat the cost of the hair because she's new at this..

After that just know that there is a risk involved because she doesn't have enough of a body of work to prove her skill level BEFORE you sit in her chair, but that doesn't mean she's not good at what she does.. However, you need to discuss with her ALL of the concerns you've had with your previous stylist. Makes sure she understands how you expect her to service you, and see if it's a fit.

Lastly Tressallure is a tape bonded extensions method similar to Protac, and as such your stylist is right that you need to use products that will not compromise the bonds. This will make your extensions last longer.. If cared for properly they should last 4-6 weeks, and if removed properly they should not cause damage or breakage..

 
There are so many different ways to apply hair extensions and these days the process is getting easier and better while not doing too much damage to your hair. Firstly, I think you should find a hairstylist that is very well trained in hair extensions and knows exactly what they are doing. There is also no need to start off big. You can always have a few extensions at the back of your hair to see how you go for the first month. That way you can see what happens to your hair and if extensions really are for you.
