But if you want to achieve a fuller hair instantly there are a lot of volumizing products that you can choose from. In this article, though, I’ll focus on the Thicker Fuller Hair Serum!

What is a Hair Serum?

Hair serums are topical applications used directly on targeted hair and scalp. Unlike shampoo and conditioner, hair serums are leave-on products and can give the instant effect you are looking for. It is specifically formulated with different ingredients that can remedy, treat, or cure fine and dull hair.

Advantage of Using Hair Serums

One advantage of using serum than taking in supplements is the long-term side effects the latter can cause. Popping in excessive supplements may have a potential toxic effect. Moreover, supplements are more costly and the effects can also take time to show.

Serums, on the other hand, are affordable and can be used and judged promptly after its use.

Caffeine is known to cleanse and invigorate hair follicles resulting in longer and wider hair roots. It also has the added benefit of blocking the DHT, a hormone primarily associated with hair loss in alopecia patients. This compound’s potential in treating hair loss is increasing over the years.

Eucalyptus globulus leaf is rich in antioxidants that can protect hair and skin from stress and damage. Its extract is traditionally used to help soothe the scalp. Furthermore, Eucalyptus globulus oil can improve hair luster and bounce in the root part of the hair.

Rosemary oil and chamomile oil (Anthemis nobilis flower extract) are powerful ingredients with anti-inflammatory and antimicrobial properties. This helps protect hair from microbial infections including dandruff, which in some cases, causes hair shedding.

The Rhatany Root Extract (Krameria Triandra) is a special astringent and protective ingredient for hair. It protects natural and colored hair from heat, radiation, chemical products, and other free radical damage.

Thicker Fuller Hair Serum Reviews

Seventy percent of users are hooked on this Thicker Fuller Hair Serum. This formula gives instant and positive results. However, there are others that got disappointed after buying. Let’s look at some of the verified user comments on this product.

Good Reviews for this Hair Serum

A lot of customers attested that the product addressed their fine and thin hair. It volumized their hair and made the hair strands look thick and shiny, too. The product is gel-like and some users apply the product in small amounts to not weigh the hair down as other gel products do. Fluffing it when dry also makes a good outcome even without blow-drying. However, thicker fuller hair gives the best results after blow-drying.

Critical Reviews about this Hair Serum

While some achieved that full, thick hair results, others did not. Well, there is no exact formula for every hair type and how much you can apply this to your hair. It depends on the compatibility of the product with your hair too. Application, as instructed, should be done on damp hair. Maybe some forgot to follow the instructions thoroughly.

Other than the non-effective results, some reported the consistency did not work well with their hair. It made their hair sticky and dry. A rare post was reported on its side effects such that it caused itchiness to the user.

Thicker Fuller Hair Serum Side Effects

The Thicker Fuller Hair Serum is generally safe and effective as attested by users. However, the serum contains naturally-derived ingredients and it is possible that you may still get allergic reactions or irritations.  Additionally, ingredients like linalool and polyethylene glycol were reported to cause allergies in some people. It is recommended to consult your dermatologist first before using the product.

Thicker Fuller Hair Serum Verdict

The Thicker Fuller Hair Serum is a great, quick fix for thinning, limp hair. It uses natural ingredients which are gentler than other volumizing products and safe for daily use. However, there are those who don’t get the same volumizing effect after using the serum.

Most volumizing products don’t work on people with super fine hair because this type of hair doesn’t hold curls and volume. The best solution for this is to address the root cause of your fine and thinning hair problem.

Check if you have deficiencies that may be causing your thin hair. Consult your doctor to help address this hair issue. Usually, using supplements can help improve your hair quality as most of the nutrients needed for hair growth can not be found in your diet.

Stress plays a big part in your overall health as well and may cause hair loss and shedding. That’s why doing activities that help manage stress like yoga and long walks can also be done to grow thicker fuller hair. Also, I recommend that you avoid using harsh products on hair like sulfate and paraben-containing products as they can damage your hair in the long run.
