Hair loss had affected people’s lives since forever when hair conditions were treated in the most bizarre ways. Fortunately for all of us, these days are gone, and now we don’t have to use crocodile or snake fats on our scalp to promote hair growth. Now all you need is a targeted serum that aims to strengthen and thicken the hair.

You’ll find dozens of hair serums formulated with active ingredients that, in theory, once they are applied to the scalp and absorbed, should encourage new hair growth. And here are the best of them!

Don’t trust false claims

However, the reality is a bit different. The treatment of androgenetic alopecia — a genetic condition and the most common form of hair loss — is not that simple. A few ingredients will not make miracles.


Why? Because they are not powerful enough to change an individual’s natural rate of hair growth thus, they will unlikely have any effects on your condition. Despite this, many manufacturers choose to hide the truth about their products’ effectiveness. They are advertising unrealistically, claiming that their products can stop hair loss and promote hair growth.

Sadly, in the end, these affirmations rarely come true. This mostly happens because the law does not require cosmetics to be cleared by the U.S. Food and Drug Administration (FDA) before going on the market. At this very moment, many products already released have not been subjected to clinical trials, so their efficacity in treating thinning hair is unproved, nor doctors have recognized them. Unfortunately, serums are not an exception to this law, as they are marked as cosmetics. 

Do serums help combat hair loss? 

True & Dorin Medical Group affirms that the scalp condition has a substantial influence on hair loss. “The best way to encourage healthy hair growth is by optimizing scalp conditions,” they affirm. A well-hydrated and conditioned scalp will encourage hair follicles to produce stronger and thicker hair that is less prone to fall.

So, if you are looking for the best serums for hair growth, you better pick one that moisturizes, revitalizes, and increases blood flow to the scalp. 

How to pick the best hair growth serum?

Even though no one can say for sure if a serum may or may not work, the active ingredients will always tell the truth. If the serum includes ingredients known to have hair growth actions, it is worth a shot. That being said, here is what you should look for in a hair growth serum:

  1. Chemical-free — you definitely don’t want chemicals in your serum, especially when so many are associated with hair loss.
  2. Antioxidants — they help hair growth by reducing the impact of oxidative stress. Oxidative stress can disturb hair follicle cycling and cause hair to break more easily. Vitamin E, green tea, and grape seed extract have high antioxidant activity. 
  3. Increases scalp blood flow — enhanced blood circulation makes hair follicles receive more nutrients, minerals, and oxygen necessary for hair growth. 
  4. DHT-blockers — if your condition is caused by the DHT hormone, you should use a DHT-blocking serum. Ingredients like saw palmetto and pumpkin seed oil are natural DHT blockers that can inhibit 5-alpha-reductase responsible for the DHT conversion. 

Don’t forget; an ideal serum must have a clean formula, moisturize, and improve the scalp’s general condition. Don’t worry. There are plenty of natural ingredients such as plant extracts, oils, herbs that, when mixed, create a perfect environment for your scalp that supports hair growth.
