"The gold standard topical treatment for thinning hair is Minoxidil, better known as Rogaine. Now, it used to be prescription only, but now it's available over the counter, and you can even get it on Amazon or at Costco. It comes in both serum and foam versions, but I recommend the foam, and I actually use the foam myself everyday. And here's a great tip from the dermatologist, Dr. Shireen Idris: you can apply it using a toothbrush to get more of it onto your scalp and less of it on your hair where it won't do anything. Now, it can take around four months or more to see a noticeable change, but I encourage you to stick with it. It works. And keep in mind that Minoxidil is toxic to cats and dogs."

"Beef tallow is filled with healthy fats, fats that are anti-inflammatory. Plus, it can be quite moisturizing to your skin and it has a lot of healthy vitamins for your skin. So, beef tallow isn't necessarily bad for the skin, but it's also not necessarily anything that will technically deage your skin. Beef tallow can be a great moisturizer, and if you like it and you don't mind smelling a little bit like a burger, then it's okay to apply it on your skin. But a couple of caveats to that. Number one, beef tallow can be comedogenic. So, if you have a history of acne, then be careful with it and make sure that you're tolerating it fine and it's not causing breakouts. Beef tallow can eventually go rancid. So, ideally, you want to go with a commercially prepared option. And the third thing is don't expect that beef tallow is going to create those changes that you're seeing in these people's skin. While beef tallow can be an effective moisturizer for your skin, it's not something that's truly anti-aging like a retinol moisturizer or other actives."

"Softwave uses ultrasound energy to heat the skin but it does it in a fractional pattern. There's a lot of online hype about this treatment, but the question is is it superior to other therapies. A lot of doctors are on board with being big fans of Softwave, but it is kind of the new treatment on the block. If you have darker skin colors, then this may be the best treatment for non-invasive skin tightening for you because some of the other treatments can cause issues with pigmentation problems in people with darker skin."

"Everyone's telling me to use Head and Shoulders as a face wash because I have fungal acne going on all around my face. Head and Shoulders is antifungal, so it helps fungal acne. You guys, it worked. Look at my skin, she's healing. I cannot believe that this actually worked, it cleared my skin in 3 days. But is this something you should try? Well, only if you have real fungal acne. Fungal acne is technically not acne like you may think it is, it doesn't create pimples, it doesn't cause breakouts. It's more of a folliculitis due to a type of fungus, and yes, this is the same type of fungus that can create dandruff in your scalp, so it's true that Head and Shoulders can treat that. Fungal acne typically presents as tiny little bumps that are often itchy, not sounding like pimples and normal acne breakouts. So if you think you have this, my recommendation would be to see a dermatologist and get that confirmed. If however you have true acne, then Head and Shoulders is definitely not a solution for you."

"There are several animal studies that do show that when animals take rapamycin they tend to live longer and healthier. Now because rapamycin is a generic drug unfortunately there will probably be very few studies on rapamycin and anti-aging because no drug company is going to fund this. But there are biohackers who are using rapamycin as a way to potentially prolong their lives. I'm not recommending it for the general population just yet. It's only available as a prescription and at this point we still need to learn more about rapamycin to be sure that this truly is an anti-aging drug, but the promise is definitely there."

"The problem with the plasma pen is that number one there's no real way to prevent that burn from going too deep and creating scarring and number two there are people who are completely untrained who are doing this not only to themselves but to other people so please please please stay away from the plasma pen."

"There are other fillers that I am definitely not a fan of and these are the permanent or near-permanent fillers such as Bellafill, Radiesse, and silicone. Now while these fillers may get you the result you're looking for at least initially, my concern is if you develop a complication. If you let's say have too much filler injected, how do you get rid of them? With hyaluronic acid fillers there is an antidote called hyaluronidase which is an enzyme that can melt that filler away, some of it within literal seconds. The problem is if you have one of these permanent or semi-permanent non-HA fillers and you get a complication like this, then you're basically just kind of screwed. You can do supportive treatments like warm compresses, like Neosporin ointment, like hyperbaric oxygen, but if you've got an intravascular occlusion and you have a part of your face that's not getting enough blood supply because that filler has clogged up that blood vessel, there's no antidote to remove that filler from the blood."

"If he has some of that filler melted away from his lips, if that filler was from hyaluronic acid, he may notice that those nerves can rebound a bit. The good thing with nerves is that they can regenerate. They can regenerate very, very slowly, but they can regenerate. It's just that they've been literally killed off, which could be a major problem for him. So stopping the filler and melting some of it away is what I would also recommend."

"Melanotan 2 is actually a black market product. It is not available for use in Europe, Canada, or the United States. It's not technically legal for use yet, but people are injecting it under their skin as a way to make their skin darker. There are major risks that can be associated with this injection, including skin cancer. It's still in a testing phase. So it sounds like they're getting experimental melanotan 2 type of injections, which is something you should definitely stay away from. Don't do it."

"Crest White Strips are little strips that you put over your front teeth that contain hydrogen peroxide and typically wear them for about 30 minutes and you do it every single day for about 10 to 14 consecutive days and every day when you look at your teeth you're going to see that they look just a little bit whiter. They've also come out with Express whitening where it's basically a white strip that is extra strong and you wear it for literally just an hour and you can see results immediately afterwards. They use hydrogen peroxide which is very commonly used for whitening of the teeth and it definitely works. They even have a complete system that you can buy that combines the express white with the regular whitening and LED whitening that's a type of light therapy for optimal results. If you've got staining of your teeth from let's say old smoking habits from drinking too much coffee or tea then this can definitely help with your teeth."

"The Foreo Bear is a microcurrent device that uses a very small electrical charge to stimulate the smooth muscles under your skin to lift and tighten up. By using this electrical current you can stimulate the smooth muscles to contract underneath the surface of the skin causing the skin to look tighter and lifted, and the results can actually be pretty impressive from these devices. If you want to turn back the clock by five years or so literally in the span of a short at-home treatment then these devices could definitely be worth your while."

"One device that does this is the CurrentBody Skin LED Hair Growth Helmet. The CurrentBody helmet contains 120 LEDs that emit a spectrum of red light that research shows can optimally penetrate the scalp and stimulate hair follicles. This range of light has been shown to support hair growth and scalp health. The helmet comes in two different sizes, and many users see stronger, denser, healthier hair in about 12 weeks. In fact, one study showed a 123% increase in hair growth. You can also combine red light therapy with topical treatments, or you can use it on its own. And as you can see from these before and after results, the improvements can be impressive. The treatments are also incredibly convenient because you can do them at home in complete privacy. Wearing the helmet is easy and you can even multitask while using it. It's FDA cleared, HSA and FSA eligible."

"LED helmets do help thicken thinning hair. These helmets work by flooding your scalp with non-heat producing LEDs. The energy from these LEDs helps hair follicles enter a growth phase. The CurrentBody LED hair growth helmet uses two clinically proven wavelengths, 620 nm to calm surface inflammation and 660 nm to penetrate deeper, energizing hair follicles, increasing circulation, and stimulating growth. Most other helmets only use one wavelength. The CurrentBody helmet has 120 LEDs for full scalp coverage, and it comes in two sizes, so you'll get a perfect fit. One study showed that in just 12 weeks, users experienced a 123% increase in hair growth and a 26% increase in hair thickness. It's super easy to use: just 10 minutes a day and you can even connect it via Bluetooth to listen to your favorite music or podcast while you treat your scalp. It's FDA approved, HSA, FSA eligible, and it comes with a 60-day money back guarantee."
"I've been using the iRestore myself for the past year and I give it my highest recommendation. Low-level laser therapy is a scientifically proven way to improve thinning hair. The light energy is like water and nutrients for the hair, absorbed by the hair follicles, and it functions to keep your hair in a growth phase. I started using the iRestore professional hair system about a year ago. It treats the majority of my scalp and I use it 25 minutes every other day, typically when I'm reading or watching TV or scrolling through my phone. I've seen it create nice changes in the thickness of my hair. The iRestore combines 282 lasers and LED lights to stimulate the hair follicles to stay in a growth phase. This FDA cleared, clinically proven technology is non-invasive, hands-free and easy to use. Results may vary, but I love that iRestore stands behind their product with a 12-month money-back guarantee."

"Not a good idea at all, horrible idea. Neosporin is an antibacterial, not only can it cause skin irritation, but you're also disrupting the microbiome on your skin, the microbiome, that are the trillions of bacteria that live on the surface of your skin. And if you use Neosporin, you're killing that bacteria, that bacteria is super important for your skin health. You do not want to do that."

"Vaseline only contains completely refined petroleum jelly, and if you look at the back of the label it's called white petrolatum, which is completely refined and completely safe to put on your skin. So feel free to apply petroleum jelly on your skin if you need its occlusive and moisturizing properties. It is safe as long as it's completely refined."

"I use a zinc oxide based cream, you guessed it a Diaper Rash Cream all over my face. Zinc oxide is gold, it will help repair your face and heal your skin while locking in hydration, and when I wake up the next morning my face is as soft and smooth as my baby's butt. If you've got really dry irritated skin, zinc oxide which is the main component in Triple Paste is a good occlusive and it can help to improve that dryness, that real irritated, unhappy type of skin that you may have. However, the group of people who should exercise caution with this face basting is if you've got acne issues, this can potentially worsen them in the wrong patient."

"It's definitely very budget-minded, which for a lot of people is really good. The good thing is you don't have a lot of fragrance, so people don't have as much reaction to something like that. But if you can afford better products, then I would encourage you to look into those. If you can't, then that's okay. I think they're reasonable."

Serums2 reviews
"I would give exosome serums right now an eight out of 10. Exosomes really are the future of skincare. These are essentially little messenger packets that will cause your skin to act in a certain way. Right now we're kind of in the infancy of exosome serums, in that they can help reduce redness, possibly improve fine lines, but I think we've got a lot in the future that exosomes can do. I would give it a nine. A lot of patients post treatment that use it say they feel like their skin heals a lot quicker, but that also is maybe attributing to the anti-inflammatory, getting rid of redness. I would say a nine, but I would knock one or two off because they're damn expensive. But it's replacing some other stuff if you look at it like that. So we carry the Plated Skin Science Exosome Serum in the office and you've seen some patients who've used that."

Now you can go to a doctor and get your labs drawn to see what you may be deficient in, or you can consider an all-in-one hair thinning supplement, one like Nutrafol.

"I actually take Nutrafol every day to treat my thinning hair. Nutrafol has now released vegan Nutrafol for women. Instead of containing animal-based collagen, it works to stimulate your body's own natural collagen using Maldavian dragon head, and this has been clinically shown to promote your body to synthesize collagen. Vegan Nutrafol also contains amino acids and minerals to add additional nutritional support for those of you who are on a plant-based diet. Like other Nutrafol products, it can take many months, four maybe six months, to see a result from this treatment, so you really have to be patient. I've heard from many many patients who swear by their Nutrafol, and I definitely recommend combining an oral supplement like Nutrafol with other modalities and topical treatments like low light laser therapy and serums."
