How Does Rennora Hair Growth Serum Work?

To get a better idea of how Rennora Hair Growth Serum is supposed to work and its method of action, it can be helpful to look at the ingredient list.

For example, Rennora Hair Growth Serum contains castor oil which has been recognized by some researchers as a substance that can improve hair luster and shine. So Rennora Hair Growth Serum may work by improving the appearance of your hair.

Rennora Hair Growth Serum also contains lemongrass which may have a soothing effect on the scalp and prevent inflammation. Inflammation in the scalp is one possible cause for hair loss.

Rennora Hair Growth Serum Ingredients – Are They Safe & Effective?

Now let’s take a more comprehensive look into the formula for Rennora Hair Growth Serum:

Grape Seed Oil

Grape seed oil is a source of substances called proanthocyanidins which may help regrow hair. The Pubmed staff reported that grape seed oil is a possible nutrient for hair growth; but they also state that more tests are needed.

Castor Oil

Castor oil is an ingredient that is often linked to hair growth and improved hair quality. However, there is only weak evidence to demonstrate that it can improve hair quality and almost no clinical evidence to suggest it can regrow hair.

Argan Oil

Argan oil is another substance that is often associated with regrowing lost hair follicles. But there isn;t enough clinical evidence to support this idea. Instead, argan oil may only be effective for protecting the follicles against oxidative stress.

Black Tea

Black tea has shown some promise in preclinical trials for promoting hair growth. Pubmed conducted a study on the hair growth effects of black tea extract and concluded the following:

Chinese black tea extract (CBTE) fermented with Aspergillus sp. significantly promoted hair growth after 2 weeks of topical application.

Neem

Neem oil is a natural substance that may be as effective or even more effective than common hair growth treatments such as minoxidil. However, the effects seem to be dependent on a combination with rosemary.

Fenugreek

Fenugreek is a natural ingredient that is claimed to benefit hair loss as a result of Androgenic Alopecia. However, the Hair Transplant Forum International staff writes that:

This review finds that while a few small studies show its efficacy, there is no strong evidence to recommend its routine use in the management of AGA.

Benefits of Rennora Hair Growth Serum

  • Improved Hair Quality – There are some ingredients in the Rennora Hair Growth Serum formula such as castor oil that may improve the condition of existing hair by increasing luster and shine.
  • Slowed Hair Loss – Some of the active ingredients in the Rennora Hair Growth Serum formula have the potential to slow down hair loss for women; but it may not actually regrow hair.
  • Oxidative Protection – Rennora Hair Growth Serum may also work to reduce the effects of oxidative stress on the hair follicles because the formula includes antioxidant-rich substances like argan oil.

How to Use Rennora Hair Growth Serum

This product comes in the form of a serum and is meant for external use only. It is to be applied directly to the scalp.

Side Effects of Rennora Hair Growth Serum

There have been some Rennora Hair Growth Serum reviews that the chebe content in the formula caused allergic reactions. However, the user was not clear as to what the reactions entailed.

Still, it would be a good idea to make sure that you’re not allergic to any of the ingredients before using Rennora Hair Growth Serum.
