Merino wool can often be found in the description of woolen clothes. Not for nothing, because thanks to its fiber size, it very rarely irritates the skin, so it is often used for clothing. The world of wool dreads also started with straight locks, at first almost only merino wool dreads could be found on the market. They were braided or twisted when they were wer to achieve a wavy effect after drying, but after another wash, the dreads take on their natural straight shape. The 18 micron fiber size results in a soft and comfortable wear. Thanks to the felting technique and fiber type, it does not shed or fluff, and no aftercare is required except for washing. You found care information in the FAQ. It can be used for years. Possible color fading may occur due to washing, UV radiation, individual use, but this can be solved with another dyeing. If you have a known allergy to lanolin, I do not recommend using it (for lanolin free hypoallergenic set contact me in pm). For the biggest look, I recommend double ended, for the most natural effect, single ended, to achieve a natural and big dread crown, I recommend single ended dreads for the hairline in 2 lines and double ended dreads for the rest areas. In the case of a full set for normal hair, 50 double ended or 80-90 single ended are usually needed from pencil-thick dreads. More if your hair is thicker, less if it’s less thick or you have a undercut. 30-45 double or 50-70 single ended are usually enough for a dreadhawk, for partial braiding I recommend 10-20 double or 20-30 single ended. Between real locks, 10 double or 20 single ended locks are recommended for bigger look or coloring purposes.
