Step 1:
Bio Purify Shampoo

The first step is the Bio Purify shampoo which deeply purifies the scalp 
by removing excess sebum. It's important to apply it twice to ensure there are no residues when applying 
it to the hair.

Step 2:
Create parting

Once we have created our parting with the tail of the comb, we proceed with the Tri Cottage parting, taking the right amount of hair, making sure not to take very voluminous sections, but a veil of hair.

Step 3:
Apply Adhesive Line

We now take out adhesive line and remove the protective film. We position our first line, maintaining it with the clips in order to create anchor points.

Step 4:
Continue The Seperation

We resume the separation that we have previously prepared, creating 
uniform anchoring.

Step 5:
Remove The Clips

We now remove the clips that were used to support our line. Let's go and apply our hair active. Let's take the other section of our adhesive line and 
apply it on top.

Step 6:
Remove Adhesive Line

We nebulize with our bioclear and use the swan to separate the adhesive lines and delicately remove the entire line.

Step 7:
Reapply

To reuse the adhesive lines, spray the entire band and remove the protein tape.

“Great salon experience at Prive and the Coldhair extensions are amazing. The installation was quick and the results look fantastic! The highlight colours blend in so nicely to my natural hair, the look and feel is so natural. I would highly recommend Coldhair extensions for either an update to your look or adding fullness to your hair.”

“I love my new extensions. It's amazing how natural they look and feel. People cannot tell the difference. The quality of the product is amazing. I also love how a little goes a long way. It only took a few pieces on either side to make my hair look twice as full. I highly recommend these and the salon.”
