Polish-Slavic Hair
Slavic hair is of Polish origin and is of the highest quality. It has a full cuticle, is very healthy, soft, shiny, and, most importantly, lightweight. It poses no problems when worn or cared for. The hair is not coated with any substances, so it does not change after washing, though it may gain a slight natural volume.
This is an exclusive and unique product. It's ideal for very demanding individuals who wear hair extensions daily or simply want the best. Since these are Polish hair, sourced locally, their structure perfectly matches our own natural hair, making them an excellent choice for those looking for seamless blending and superior quality.
The wear time for Slavic hair extensions is a minimum of 6 months, and in most cases, with proper care, up to 3 years. Every 3 months after application, the hair should be removed. Before reapplication, the hair needs to undergo regeneration and new bonds should be prepared according to the chosen method. We offer these services for a fee, and the hair can either be sent to us or brought in personally.
They are primarily available in uncolored versions, covering the entire range of natural shades from blonde to black. Since these are locally sourced hair from Poland, most of them come in a medium blonde color, commonly known as "ash blonde." We often dye the hair to match the client's hair color upon request, including creating ombre effects.
sometimes even a thin bundle with a small weight is enough For hair thickening,
For hair extensions, the amount should be proportional to the amount of hair you naturally have in order to achieve the most natural effect. The thickness of your ponytail should closely match the amount of hair you're planning to attach. If the right thickness isn't available in the offer, you can combine bundles with the same structure to achieve the desired volume.
These are natural Polish hair with a full hair cuticle. They are not coated with any substances, do not change after washing, and do not tangle. Each bundle is unique because it comes from one individual, with different lengths, weights, and textures. They are often children's hair, healthy, and above all, lightweight. GrzechHair's Polish-Slavic hair is thoroughly brushed, ensuring very thick ends in each bundle, which distinguishes our hair on the market. To make the selected bundle suitable for hair extensions or thickening, it needs to be processed according to the appropriate method.
- We can divide the bundle into strands and process the ends with keratin for i-tips, flat tips, mini flat tips or nano-rings.
- sew it onto a tape or tape with clips.
- create a seamless Clip-In set.
- convert it into Tape-in strips of 2cm, 3cm, or 4cm in standard or sewn versions, as well as biotape.
- Dde it to any color.
The price list for hair processing is available in the "hair customization" section.
