Shrinkage is one of the most universally experienced and discussed phenomena in the natural hair community. It refers to the dramatic difference between the length of natural hair when stretched or dry and its length when wet or in its natural, shrunken coiled state. Tightly coiled textures like 4B and 4C can experience up to 75 percent shrinkage — meaning hair that is twelve inches long when stretched may appear to be only three inches long in its natural state. While shrinkage is a sign of healthy, well-moisturized natural hair, there are numerous techniques for stretching and elongating natural hair without heat when a longer-looking style is desired.
Understanding Why Natural Hair Shrinks
Natural hair shrinks because each strand is coiled in a spring-like curl pattern. When the hair is dry, the natural tension of the coil causes the strand to contract to its resting length, which is significantly shorter than its fully stretched length. When the hair is moisturized or wet, the weight of the water and product temporarily elongates the coil, which is why natural hair appears longer when wet. As the hair dries, it contracts back to its natural coiled resting length unless a stretching technique is applied to prevent it.
Technique 1 — African Threading
African threading is an ancient hair stretching technique in which sections of hair are wrapped tightly with thread from root to tip, preventing the hair from contracting as it dries. The thread is removed after the hair is fully dry, revealing long, stretched sections with minimal shrinkage. This technique produces excellent elongation without any heat and is particularly popular for children’s natural hair.
Technique 2 — Banding
Banding involves placing multiple small elastics or bands along the length of individual sections of hair while they are damp, spacing them evenly from root to end. As the hair dries, the bands prevent the sections from contracting, stretching the hair to a longer length. Remove the bands once the hair is fully dry to reveal stretched sections. Banding is one of the quickest and most accessible shrinkage-reduction techniques and requires no special tools.
Technique 3 — Braid Out or Twist Out
Setting the hair in braids or twists while damp and allowing them to dry completely before releasing is one of the most popular methods for stretching natural hair while also creating a defined wave pattern. The braid or twist sets the hair in a stretched, elongated configuration as it dries, and when released, the hair retains much of that stretched length while also showing a beautiful, defined pattern.
Technique 4 — Protective Styling
Long-term protective styles such as braids and twists with extension hair keep the natural hair stretched for weeks at a time. When the protective style is removed, the natural hair often retains some of the stretched length for several days before fully reverting to its natural coil pattern.
Final Thoughts
Shrinkage is a healthy and natural characteristic of natural hair, and embracing it as a sign of well-moisturized, elastic hair is a positive perspective shift. However, for occasions when a longer-looking style is desired, the heat-free stretching techniques described above offer effective and hair-safe alternatives to heat for managing and minimizing shrinkage on natural hair.
