SAS is usually noticed in children around 2-4 years of age and is considered a benign condition. [Short anagen syndrome (SAS) is a condition in which hair does not grow long.

- Hair Breakage: If your child's hair is constantly being pulled, brushed harshly, or subjected to other forms of damage, it might appear that the hair is not growing, even though it might be. [Additionally, hair breakage and damage from brushing, styling, or environmental factors can result in uneven lengths.]
- Nutritional Deficiencies: A lack of certain vitamins and minerals can affect hair growth. For example, a deficiency in zinc, iron, or biotin can slow hair growth.
- Underlying Medical Condition: In rare cases, slow hair growth could be a symptom of an underlying medical condition, such as thyroid problems or an autoimmune disease.
It's important to consult with your pediatrician or a dermatologist to determine the cause of your child's slow hair growth. They can assess the situation and recommend appropriate treatments, if needed.
