I've seen it probably 20 to 30 times if I were to guess, because sometimes patients come and say, 'Hey, I'm here for hair loss and I've had this breakout recently,' and we put two and two together and figured it out. Another important factor to note: A Food and Drug Administration FDA warning was issued stating that taking biotin supplements, especially in higher doses, can interfere with the accuracy of lab test results, citing the example of testing for troponin , a biomarker to diagnose if you're having a heart attack.
Biotin can interfere by producing low troponin results, creating a false negative. If you're looking to grow your hair or increase thickness, instead of heading directly for a pill or chewable supplement, it's important to determine what could be causing the lack of growth.
Sometimes conditions that may seem inconsequential could indicate a bigger issue, which is why you should consult a professional. Bhanusali recommends getting your iron levels checked and taking 5, IU international units of vitamin D3 per day, as some studies have suggested it can help patients with female pattern hair loss.
Topically, Gross suggests using the ingredient minoxidil, widely known by the brand name Rogaine. It's the only topical ingredient proven to grow hair.
Colaco also suggests small changes, like giving your hair a break by limiting hot tools and professional chemical services like coloring, perming, and relaxing your hair, and avoiding tight hairstyles, smoking, and low-calorie diets. If you're nurturing your hair and are still experiencing hair loss, there are in-office treatments to consider — specifically laser and platelet-rich plasma PRP , which is recommended by Gross and Bhanusali.
Samolitis suggests blood tests to indicate if you have a hormonal imbalance that may require something like a DHT dihydrotestosterone, a metabolite form of testosterone blocker that can be applied topically.

Does Biotin Help Prevent Hair Loss? How Long Does It Take Biotin To Work On The Hair? Symptoms of Biotin Deficiency If you're worried and wondering whether you might have a biotin deficiency, here are some signs to look out for : Brittle, thinning hair - Lack of biotin can cause weak, brittle hair prone to breakage.
Noticeable hair loss typically occurs in patches. Dry, scaly skin - Biotin deficiencies often lead to itchy, red rashes on the face, mouth and genital area.
Cracked lips are another indicator. Weak, brittle nails - Without enough biotin, nails become softened and split easily.
Ridges or grooves may also appear. Fatigue and muscle pain - Biotin activates enzymes involved in energy production. Deficiency can lead to exhaustion, aches, and cramps.

Those taking certain seizure medications - Some of these drugs have been shown to lower biotin levels over time. Heavy alcohol drinkers - Too much alcohol can damage your digestive system and get in the way of absorbing biotin.
Longtime smokers - Years of smoking may drain biotin reserves and make deficiency more likely. Older adults - As we age, our bodies gradually get worse at extracting and using biotin from what we eat.
How Much Biotin Should You Take? What Types of Biotin Are There? Biotin-Rich Foods Enriching your diet with foods filled with biotin is a tasty way to maintain healthy levels.
Some delicious choices include: Eggs: The egg yolk is a biotin jackpot. Scramble up some eggs for breakfast or make an omelette for dinner. Salmon: This fish packs a double punch with biotin and omega-3s.
Fire up the grill or bake a salmon filet with lemon and herbs. Avocado: The smooth, creamy green goodness of avocado is a biotin blessing. Mash it up on toast or dice it into salads. Nuts and seeds: Snack on a mix of almonds, walnuts, sunflower and pumpkin seeds for biotin galore.

Discontinue use if any swelling, breathing issues or severe rashes develop. High biotin doses can skew lab test results, leading to incorrect high or low values.
Let your doctor know about any supplements. Excessive biotin intake from mega-dose supplements may theoretically contribute to higher blood sugar levels and thyroid issues. Moderation is key. Other medicines can affect how our body uses biotin.
Consult a doctor about potential interactions. Those with a history of seizures should use caution, as biotin may potentially lower the seizure threshold in some people.
