And yeah, i am wondering if i am using the wrong tool because it basically comes up with its own line as i move the pointer, rather than allowing to go in and out of the hair and such. i did apply feathering but apparently it was already gone pretty much on the cut out.
Yeah, the "right" tool for cutting a person (or anything else) out can change from image to image, depending on the image itself.
Speaking with Photoshop in mind (I've never used Elements, so I don't know what it has vs what it doesn't, compared to PS), sometimes the pen, sometimes a quick selection, sometimes a color range selection, sometimes a channel selection, oftentimes, combinations of more than one applied to different areas is the best way to go. For each, there are other tweaks that can be made in conjunction with them to make them select more accurately what you really want to select. There are even times when a simple brush and a mask work well.
Always make the selection, then apply it to a mask, so that it can easily be revised later if needed.
EDITED TO NOTE: Apply the selection to the mask, rather than using it to delete the pixels you think you don't want. Use the mask to hide or reveal areas at will. If you delete stuff around the subject, it's just gone, and you get those horrible sharp cut lines.
Again, with Photoshop in mind, from there, drop in a background on a layer below, then if needed (usually) jump back up to the masked layer of the subject and refine the mask's edge with any or all of the following: shift, feathering, contrast, and decontaminate. The edge detection tool works great on hair.
EDITED TO NOTE: Again, the feathering and stuff happens to the MASK, rather than to a cut out image of the subject pasted onto a background. It makes a huge difference, especially when it comes to make it all blend together in a natural-looking way.
From there, you may need to adjust color, hue and brightness of either the background or the subject to get them to appear to fit together more naturally, keeping in mind that subjects tend to pick up a little color from their surroundings, and backgrounds in particular tend to reflect a bit around the subject's edges.
