Yes, based on the provided reference, growth hormones can affect hair.
Research indicates a connection between growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels and hair health. These hormones play various roles in the body, and their levels can influence hair growth cycles.
According to clinical observations, changes in the levels of these hormones have been linked to different effects on hair. The specific nature of the change and its cause appear to be significant factors.
Key Findings from Research
The provided reference highlights several key associations between GH and IGF-1 levels and hair conditions:
- Primary Decreases: Clinically, primary decreases in GH and IGF-1 have been associated with hair loss and alopecia [36]. This suggests that when levels of these hormones are low due to primary issues, it can contribute to hair thinning or loss.
- Decreases due to GHRH Deficiency: Interestingly, decreases in GH and IGF-1 due to GHRH deficiency have not [been associated with hair loss/alopecia] [42]. This indicates that the cause of the hormone decrease may matter, and not all reductions in GH/IGF-1 levels necessarily lead to hair loss.
- Elevated GH Levels: Conversely, hair growth stimulation has been seen in acromegaly patients [35]. Acromegaly is a condition characterized by the overproduction of growth hormone, suggesting that higher-than-normal GH levels can promote hair growth.
In summary, the relationship between growth hormones and hair is not simply a matter of presence or absence but depends on the hormone levels and potentially the underlying cause of the change. Low primary levels may lead to loss, while high levels may stimulate growth, as observed in specific clinical contexts described in the reference.
