"S-Braided Bulk: P27/30/4" is a designation for a type of bulk braided hair. This specification includes color shades P27, P30 and 4. The "P" in front of the numbers probably stands for "piano", a method of mixing colors in hair extensions where the colors are arranged side by side like keys of a piano. P27 is typically a honey blonde, P30 a medium golden blonde, and 4 a dark brown color. Together, these shades create a harmonious, multi-dimensional color combination, ideal for those looking to add depth and variety to their braided hairstyle.
