After an eyebrow transplant, many individuals anticipate instant, uniform results—but the truth is growth patterns to fluctuate dramatically due to changes in internal hormone levels. Hormones are critical in controlling the hair growth cycle, and even after follicles are grafted, their development can still be strongly influenced by imbalance of estrogen, testosterone, thyroid hormones, and cortisol.

Consider this: an increase in androgens such as testosterone may result in denser hair growth, making transplanted eyebrow strands appear unusually strong than anticipated. On the flip side, reduction in estrogen—frequently observed during pregnancy, postpartum, or menopause—can induce hair follicles into the resting phase prematurely, leading to temporary thinning. This is not evidence that the transplant was unsuccessful; it merely reflects that your body’s internal chemistry is altering the natural rhythm of the new hairs.

Thyroid disorders can also distort the anagen phase of transplanted follicles. Patients with unmanaged thyroid conditions may experience spotty growth or prolonged fallout for months after surgery. In the same way, chronic stress that spikes cortisol can induce telogen effluvium—a condition where an unusually high number of hairs, among them transplanted ones, enter the resting phase and fall out.

Remember that that eyebrow transplants involve relocating hair follicles from one area to another, yet the grafted units still are sensitive to the hormonal signals of their destination area. Even if the donor hair was harvested from the scalp, once placed in the eyebrow zone, it becomes attuned to local hormonal cues. This adaptation can last up to six months and could fluctuate until your endocrine system returns to equilibrium.

Should you notice unpredictable changes in your transplanted eyebrows, you should consider consult your physician to test your hormone profile—especially if you’re also experiencing symptoms like low energy, sudden weight fluctuations, or textural changes in your skin. Correcting underlying hormonal disorders often reinstates normal growth patterns. During this period, patience is non-negotiable—eyebrow transplants typically require up to a year to mature, and کاشت ابرو در تهران cycles during this time are common.

Practicing a well-rounded regimen, actively managing stress, and keeping follow-up visits with your surgeon can enhance your results. While hormones may guide your recovery journey, they rarely dictate the final outcome. Given time and proper attention, most transplanted eyebrows will develop into a natural and enduring look.
