What Is Algae Extract?

Algae extract is obtained from the four major seaweed classes: red algae, brown algae, blue-green algae, and green algae. It contains an abundance of vitamins and minerals that make it a beneficial treatment for hair loss.

Benefits Of Algae Extract For Hair

Algae extract has some significant benefits for hair:

Dandruff Control

Malassezia is the fungus scientists believe to be the main underlying cause of dandruff. It feeds on the natural oils produced by the body.

Thankfully, dandruff can be managed by specially formulated products containing the active ingredient Zinc Pyrithione.

When this is paired with a natural ingredient such as algae extract, you can enjoy healthy nourished hair and a scalp free from dandruff.

Manages Oil Production

Algae extract can reduce oil production on the scalp.

It can help an overly oily scalp by rebalancing the microbiome.

An overproduction of oil on the scalp may be a sign of other issues. It may therefore be a good idea to consult a dermatologist if you are worried about this issue.

Clean and Healthy Scalp

Algae extract is an excellent clarifier for hair.

If you tend to use a lot of styling products, then you may experience product build-up. This build-up can clog the pores on your scalp which can inhibit healthy growth at the roots.

It also prevents cuticles from absorbing moisture. This can leave hair dry and more prone to damage.

Algae extract can remove this residue of hair product and leave hair feeling clean and hydrated.

Paired with an exfoliator for your scalp, problems caused by product build-up will be a thing of the past.

Hair Nourishment

Algae extract contains lots of nutrients that benefit hair health overall.

Some of the key nutrients are iron, potassium, calcium, magnesium, vitamins A, B1, B6, B2, C, and niacin.

When used as an ingredient in hair care products, algae extract can provide a topical supplement for hair ensuring it gets all the necessary nutrients.

Scalp Nourishment

Algae extract is used as an anti-irritant in many products. It can therefore be used to soothe an irritated or inflamed scalp.

The antioxidants present in algae extract can really benefit the skin on the scalp. A healthier scalp means healthier stronger hair that looks great.

Shine and Hydration

Algae extract can improve suppleness and hydration in the scalp as it minimizes the breakdown of acid within the skin.

When the scalp stays hydrated, this, in turn, promotes moisturized healthy hair.

Some algae extracts, such as Himanthalia Elongata and Atlantic Kelp, can be used to fight hair loss. These extracts contain antioxidants to heal and nourish the scalp.

Algae extract can reduce scalp inflammation triggered by bacterial infections. This is due to its antiviral and antimicrobial properties.

Along with this, it can reduce the activity of 5-alpha reductase that causes hair loss.

The abundance of nutrients it contains nourishes a damaged scalp thus promoting hair growth. The nutrients also contribute to the hair having high shine and being fuller and stronger.

How Does Algae Extract Prevent Hair Loss?

Early studies have shown that patterned hair loss can be fought with specific species of seaweed.

For instance, fucoidan, found in brown seaweed species, is already used to increase blood flow as a treatment for people with heart disease.

In theory it also works to increase blood flow to the scalp. Further research needs to be conducted into how fucoidan benefits hair growth, but the early results are very encouraging.

How To Use Algae Extract For Hair

There are two main methods of enjoying the benefits of algae extract for your hair:


Algae extract can be applied topically which is the most beneficial method to treat the scalp.

There are plenty of products available that boast algae extract as one of their ingredients.

Experts do not advise applying algae extract directly to the scalp but rather using products that contain the ingredient.


An oral supplement also has benefits.

Rich in vitamins, minerals, and omega-3 fatty acids, an oral supplement of algae extract complement a well-balanced diet to give strong and healthy hair which thrives.

What Nutrients Does Algae Extract Contain?

Algae extract is an excellent source of vitamins such as vitamin A, B1, B2, B6, B12, C and E. It also contains minerals such as potassium, iron, magnesium, calcium, and iodine.
