For the majority of clients, you will need at least 5 packs or 100 strands of hair extensions. If you aren’t sure, I recommend first booking a consultation with a stylist to get a professional evaluation.

For fine/thin hair, from your occipital bone down, it will take about 50- 60 strands; from your occipital up to the crown of your head, it will require 50-60 strands.

Alternatively, medium/thick hair from your occipital bone down will require 60- 80 strands; from your occipital bone up towards the crown, of your head it will require 50-80 strands.

A general rule of thumb to remember is if the client’s hair is thicker or shorter, chances are you will require more packs of extensions in order to be able to blend them in naturally.

How Do You Clip In A Full Head Of Extensions?

How To Apply Full Head Of Clip In Hair Extensions (3 Rows)

As mentioned before, you will need 5-9 packs for a full head of clip-in extensions. It is very important to know how to clip in your extensions correctly so that they are not visible to the naked eye and so that they blend properly.

The best way to install clip-in extensions on a full head for a natural appearance is to make sure that you use the 3-clip wefts for the back of your head, and 4-clip wefts or higher should be used for the middle of your head or the highest point of your head. This leaves the 2-clip and 1-clip wefts for the front of your head.

Here is a full guide on how to clip in a pack of 10 pieces:

Step 1.

Wash, blow-dry, and style your own hair before you start. Ensure that your extensions are also washed, dried, and styled separately to fit your own hair.

Step 2.

Separate a thin section of hair at the nape of your neck and tie or clip the rest away.

Step 3.

Take a weft of 3 clips, measure it to your head and make sure that that piece fits your head perfectly and is not too long. Clip the middle clip on the weft to the center of your head as close to the root as possible. After that clip the left and the right side in as well. Ensure that it does not stick out past your hairline.

Step 4.

Untie the hair that was clipped up and gently brush through it without pulling on the clipped in extension. Separate a thin line above the clipped in the weft, make sure that it is a straight line and clip the remainder of the hair away.

Step 5 .

Measure the wefts to your head and use the piece that fits the best. Attach the piece to your head the same way as you clipped in the previous weft. Make sure the middle clip is in the center of your head and you have clipped it in as close to your roots as possible.

Step 6.

Separate the next part of your hair, it should be a straight line from ear to ear. The hair you have separated should be covering the previous clip that you clipped in. You are then going to clip the remainder of the hair away.

Step 7.

You are now going to use your largest weft in your pack, usually one with 4 clips. Measure this piece to your head and make sure it fits your head perfectly. This time you are going clip the 2 middle clips on the weft to the center of your head and the after that clip the sides as well.

Step 8.

You are going to repeat the separation process above the big weft you just clipped in. Use a 3 clip weft, measure it to your head, and then clip it in the same way you clipped the others in. Remember to clip the clips as close to your roots as possible and that the middle clip is at the center of your head.

Step 9 .

You are now going to move to the front of your head. Separate the hair 2 inches above your ear in a straight line and clip the remainder of the hair away.

Step 10.

Take your 2 clip weft and clip the clip closest to your hairline in first. Make sure that you do not clip it to close to your hairline that causes it to visible and secure the second clip.

Step 11.

Separate the hair above your 2 clip weft and clip the rest of the hair away. Take a 1 clip weft, clip it to any piece of hair in that section close to the root. Take the next 1 clip weft and clip it anywhere under the clips, close to your ear to fill any gaps.

Step 14 .

Repeat the same process on the other side of your head and you are done!

You can adjust the size or amount of wefts you use depending on your own hair’s thickness. If you use fewer pieces you will have to adjust it the process to the number of pieces you have.
