Wanna need different methods to apply?

Different methods of applying hair extensions:

Braids, Cornrows, Twists, Locks - Integrates extensions in a visible way in that the braided attachment is seen but blends into the hairstyle.

Weaves - Tiny braids hold hair extensions against the scalp, like cornrows, except these braids are hidden. A concern with this method is that it applies tension and uneven weight to the natural hair where attached, especially when washing the hair or when wet from swimming or other activities. This can not only loosen the weave but it can tug on your natural hair and break it. It can also be difficult to dry the hair beneath the braids and some people will avoid washing their hair as often.

Bonding - The extensions used for this method have a latex plug meant to be glued to your own hair for short terms use. Because this method is fast it's also inexpensive. However, to remove extensions, oil and heat must be used to dissolve the bonding agent, which messy and time consuming. If not removed with care the latex can pull your own hair out.

Metal Tubing - Uses a metal tube clamped over the real hair to attach extension hair. In some cases it can break off real hair, can be difficult to pry open later, and adds additional weight to hair. Experts don't recommend this method for fine hair.

Heat-Shrink Tubing - This method won't harm natural hair but doesn't have a lot of adhesive for holding power needed for extended wear. After a few washings, the tubes can loosen, releasing strands, which then allows even more extension hair to fall out.

Adhesive-Based Fusion - This method is arguably the best, though the type of adhesive used is critical. Wax-based adhesives have a low melting point so a professional grade adhesive is a must. These adhesives can withstand both heat and chemical treatments. The adhesive remover that is used to remove the hair extensions dries the bonding agent to a powdery substance (rather than dissolving it through messy oil and heat).

If interested in hair extensions speak to 2 or 3 professionals about your specific needs and concerns and get a written estimate of what they would do and how much it would cost. New methods will no doubt come to light and it's always wise to get more than one opinion before committing to something that will represent a substantial investment of time and money.
