Viviscal.

"Viviscal works by supporting the hair follicle environment and growth cycle from a nutritional standpoint. It can be especially helpful for gradual thinning, stress-related shedding, or postpartum hair changes. Standard Viviscal is a solid budget-friendly option. If you want results, use it daily and give it at least 3 months. You want to support it with adequate protein, sleep, and scalp care and health."

"Viviscal is another popular hair growth supplement that also contains hydrolized marine collagen. While viviscal does contain this lovely amino acid blend, it does have fewer ingredients than other options, which can make it more suitable for somebody who's already taking a bunch of other vitamins and minerals or adaptogens and they may not need all of that. For people who want to play it safe, viviscal may be just a better option for them."

"There are a few vitamin supplements that I recommend to my patients if they ask me for recommendations that can potentially support their hair regrowth journey, and that's Nutrafol and Viviscal. Both of those do contain biotin, but it's not the biotin that's actually helping. It's their proprietary blend of active ingredients that is supporting that hair regrowth."

"Viviscal does contain biotin, amino acids, various B vitamins, as well as plant-derived extracts like millet seed extract and horsetail stem extract. Viviscal does have a few double-blinded randomized control studies demonstrating efficacy, especially for androgenic hair loss. Interestingly, when studying their hair loss, individuals taking Viviscal had a noticeable improvement in the overall health and strength of their nails as well as fuller eyebrows and improvement in skin hydration. One thing to be careful of is that Viviscal does contain biotin, and so if you end up taking Viviscal for hair thinning, you want to notify your providers if you ever undergo testing, specifically like cardiac and thyroid testing, because biotin can interfere with those labs."

"Something I like about Viviscal, and the reason I tend to recommend it to my patients, is because it has done clinical testing to show that their supplementation is actually effective for hair growth. So it's not just theoretical, but the people who have taken this supplement have actually seen benefits in their hair."

"If you are going to go the supplement route pick a supplement that has been vetted and has gone through clinical trials. The two hair growth supplements that I recommend the most in my practice are Nutrafol and Viviscal. To my knowledge these two supplements have not been compared head-to-head but they both have clinical trials showing successful hair growth when taking them for six months or more."
