Study, Trial or Testing Result Summary

Members OnlyHuman studies

This product is apple cider vinegar from ZHOU, and the label does not state how much apple cider vinegar is in each serving. We found no human studies testing apple cider vinegar for hair, whether for hair growth, thickness, shine or scalp health. Because no studies were found, we cannot say whether this product helps hair, what amount might be needed, or how long it would take to notice any change. The only support comes from customer ratings. About 7000 shoppers rated the product, and 93 percent of those ratings were positive. However, we could not read any written reviews, so we do not know whether those ratings mention hair at all or relate to other reasons people take apple cider vinegar, such as taste, digestion or general wellness. High ratings alone do not show that a product works for a specific goal. Without studies on hair and without written reviews describing hair results, the evidence for this goal is thin. Anyone wanting help with hair loss or thinning should treat this product as unproven for that purpose and may want to talk with a doctor about options that have been tested. Animal and cell studies are never counted.

Biohacker Summary

Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it

Apple cider vinegar is a smaller ingredient in this product, and it is the only one the panel discussed. Most of the panel uses or recommends it, mainly to blunt blood sugar spikes, and they usually take it with or just before meals, with doses of one to two tablespoons, often diluted in water. Other reasons include digestion, easing stomach acid problems, better sleep after a late meal, and using it in salad dressings or vegetable dishes. Cautions came from two of them: one said liquid vinegar worked for blood sugar where pills did not, called the gummies overhyped, and advised diluting it to protect teeth, and another said it is high in histamine and may make some people feel worse in the morning.
