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.
