We explored how zinc acetate hydrate impacts hair loss for patients experiencing symptoms after COVID-19. In our analysis, we looked at 120 symptomatic outpatients over 12 weeks, observing their recovery patterns and any improvements in their symptoms. The focus was on various lingering effects, including fatigue and hair loss, particularly how zinc could potentially alleviate these issues.
Our findings highlighted significant improvements in hair loss for those treated with zinc acetate hydrate at multiple checkpoints (4, 8, and 12 weeks) compared to those who did not receive this treatment. The results were statistically significant and suggested that zinc could be a useful option for those struggling with hair loss post-COVID-19.
Additionally, we noted improvements in fatigue among those receiving zinc, although this was not as pronounced at all time intervals. As a whole, our study emphasized zinc's beneficial effects, particularly for hair loss, providing promising insights for anyone dealing with these challenging post-viral symptoms.

Zinc's limited impact on hair loss
We explored the impact of zinc on hair loss, focusing on its isolated effect rather than in combination with other treatments. Through the study, we carefully examined how zinc supplementation can influence hair health and address thinning or loss.
Our findings revealed that while zinc is often suggested as a potential remedy, the evidence supporting its effectiveness for hair loss was limited. The study did not find strong results indicating that zinc alone had a significant positive impact on hair regrowth or thickness.
This highlights the need for further investigation into how zinc interacts with other factors that might contribute to hair health. Therefore, while zinc might play a role in some instances, we should approach it with a balanced view regarding its effectiveness in tackling hair loss.

Zinc deficiency linked to hair loss
We investigated the connection between zinc levels and hair loss among Kurdish adults, focusing on various hair loss types like alopecia areata and telogen effluvium. By examining a group of 125 individuals with hair loss, we compared their serum zinc levels to a control group of 75 age and sex-matched healthy subjects.
Our findings revealed that individuals experiencing hair loss had significantly lower levels of zinc in their blood compared to those without hair loss. Interestingly, the group suffering from telogen effluvium exhibited the lowest zinc levels in our study. We also noted that a portion of those with hair loss experienced severe or mild-to-moderate zinc deficiency, a stark contrast to the control group. Overall, our research indicates that zinc deficiency may play a role in contributing to hair loss in the Kurdish population, especially for conditions like alopecia areata and telogen effluvium. Therefore, maintaining healthy zinc levels could be vital for hair health.

We designed a microneedle patch that contains zinc and curcumin, aiming to assess how these ingredients work together to promote hair growth. In our study, we utilized two different animal models to examine the effectiveness of this patch. One model represented androgenic alopecia (AGA), and the other focused on wound healing.
By delivering bioactive zinc particles directly into the skin, we explored how this method could enhance hair regrowth. Our findings showed that the zinc-curcumin combination significantly improved the viability of certain skin cells and countered the negative effects of common hair loss factors, like excess reactive oxygen species and dihydrotestosterone.
Most strikingly, the treatment not only encouraged hair regrowth in the AGA model but also facilitated wound healing. We noted an increase in hair follicles and better cell proliferation, which points to zinc's potential role in supporting both hair health and skin recovery. Overall, our research suggests a promising direction in the use of zinc for addressing hair loss and skin healing more effectively than traditional methods alone.

Zinc's potential in hair loss treatments
We explored the effects of an oral supplement containing zinc, arginine, l-cystine, and vitamin B6 on patients suffering from telogen effluvium (TE), a common type of hair loss. Over three months, we followed 20 individuals who took the supplement four times daily.
To measure the treatment's effectiveness, we assessed hair growth in several ways, including clinical evaluations and trichoscopy, which checks hair density and width. After the treatment period, we noted significant improvements, with patients reporting positive changes and researchers observing increased hair quantity and diameter.
While zinc is one of the key ingredients in the supplement, the overall improvement we saw is due to its combination with other nutrients. Therefore, isolating zinc's direct effect specifically on hair growth is challenging. It seems that this supplement could be a useful addition to managing TE, but we cannot conclude solely on zinc's efficacy without further targeted studies.

We examined the connection between serum zinc levels and alopecia areata (AA), an autoimmune condition that causes hair loss in about 0.5% to 2% of the population. Our research analyzed 34 studies involving nearly 5,000 participants across 16 countries to understand how zinc might influence AA.
Our findings indicated that people with AA had significantly lower levels of zinc compared to healthy individuals. Specifically, there was a notable difference of about 0.69 micrograms per deciliter, suggesting a potential link between zinc deficiency and the risk of developing this condition. Additionally, we discovered that a deficiency in vitamin D was also associated with an increased risk of AA.
While these results hint that zinc supplementation could play a role in treating alopecia areata, it's important to note that we did not isolate zinc treatment from other variables. Therefore, while we found a connection, we cannot definitively say that zinc alone will resolve hair loss issues for those affected by AA.
In conclusion, our research emphasizes the importance of monitoring micronutrient levels like zinc and vitamin D in relation to alopecia areata. More focused treatments could emerge as we continue to explore these relationships.

Perfectly fills the deficit! I purchased a high dosage of zinc picolinate at 50 mg due to a zinc deficiency found in my hair analysis. The doctor suggested this dosage. I noticed a significant reduction in the white dots on my nails, dryness, and hair loss as I consumed it. I also take it during colds, 1 capsule daily for 5 days, alongside vitamins C, D, and black elderberry, which hastens recovery. Zinc is essential for maintaining immunity, especially when combating viruses, though lower doses of 15 to 25 mg are sufficient for daily use.

Stopped hair loss
Helped against hair loss. The doctor prescribed zinc after my hair started falling out post-coronavirus, with tests showing critical indicators. Within three days of starting zinc (and other supplements), hair loss ceased! It felt miraculous, as I feared going bald. I recommend it, but only after proper testing and under a doctor's supervision.

Our investigation focused on understanding how zinc levels are connected to chronic telogen effluvium, a condition that causes significant hair loss. We conducted a case-control study involving 100 individuals, split into two groups: those diagnosed with chronic telogen effluvium and healthy participants matched by age and gender.
We examined levels of zinc in both hair and serum samples. The findings revealed that individuals with chronic telogen effluvium had notably lower zinc levels compared to their healthy counterparts. Additionally, there was a positive correlation between zinc levels in hair and serum, which suggests that tracking these levels might provide insights into managing hair loss effectively.
Overall, our results suggest that zinc deficiency could play a role in hair loss associated with chronic telogen effluvium. While we did not assess a direct treatment intervention, the findings highlight the importance of maintaining adequate zinc levels for hair health.
