Re-Nourish Reviews – Should You Buy Dr. Al Sears MD ReNourish Hair Formula?

Do you find yourself cleaning up after a lot of hair loss? Not sure where you fall short in ensuring the nourishment of hair follicles? Although losing hundreds of strands is natural, continued losses imply the need for change, whether in lifestyle or eating habits. Dr. Sears believes one topical treatment will suffice if these adjustments only have a minor impact. Fuel is essential for our hair follicles, and this expert has created a serum that requires a couple of sprays per day to improve hair health—interested in learning more? Here’s a detailed review of Re-Nourish.

What is Re-Nourish?

Re-Nourish is a hair regrowth serum designed to nourish thinning hair, sustain healthy hair, and encourage existing hair growth within the first eight weeks of use. This doctor-formulated solution combines stem cell therapy and essential nutrients reckoned to feed starved hair follicles, hence the name, Re-Nourish. Considering this brief introduction, we must all take a step back to appreciate the groundwork on which the Re-Nourish serum was built before looking more closely at the ingredients and how they enhance hair health.

How Does Re-Nourish Work?

According to the formulator, Dr. Al Sears, chronic stress blocks a critical factor that ensures consistent cycling of the different stages of hair growth. Alas, the blockade extends the telogen stage, commonly known as the shedding stage, by five times, resulting in increased bald spots and thinning hair. Stress has been shown to weaken stem cells (i.e., a bulge in which the lower stable portion of hair follicles, interfollicular epidermis, hair follicle structures, and sebaceous glands lay), consequently causing further damage.

The blocked constituent is Gas6, a protein called hair’s best friend. Based on existing studies, no matter one’s current state, adding Gas6 suffices to activate hair follicle stem cells to escape the shedding stage of the hair cycle and enter and remain in the growth stage for as long as they can. Now that we’ve established the foundation of Re-Nourish let’s turn our attention to the main anti-stress ingredients.

What’s Inside Re-Nourish?

The Re-Nourish serum comprises many things, but the main ingredients that rest at its core include:

Panax Ginseng Root

Panax ginseng root is a perennial plant that grows primarily in East Asian mountains. It functions as an adaptogen, which means it helps the body resist stressors. In terms of hair health, invitro research has revealed that ginseng may support a healthy transition between the telogen and anagen stages, extending the time stem cells spend in the growth stage and boosting the size and thickness of hair follicles.

D-Alpha Tocopherol

D-alpha tocopherol is a naturally occurring vitamin E or fat-soluble molecule found primarily in plant oils. Vitamin E is a vitamin and antioxidant protection from internal and external toxins. In terms of hair health, this substance is used topically to treat dry hair and a dry scalp. Matter-of-factly, vitamin E has been shown to boost circulation to the scalp, allowing blood to travel to critical areas to help enhance the strength of hair follicles. Another study underlined vitamin E’s antioxidant activity, stating that it aids in reducing lipid peroxidation and oxidative stress in the scalp.

Organic Nigella Sativa

Nigella sativa, often known as black cumin or black seeds, is a medicinal herb widely used in the eastern Mediterranean, northern Africa, southwest Asia, and the Indian subcontinent. This ingredient has been used to treat various health conditions, including swollen joints, asthma, bronchitis, type 2 diabetes, and heart disease. Nigella sativa contains antioxidants crucial for strengthening the immune system and preventing the detrimental effects of oxidative stress, and it is also recognized for its anti-inflammatory and cognitive outcomes. Applying black seed oil could promote hair growth, reduce hair fallout, and treat temporary shedding.

Fenugreek Seed

Fenugreek is an herb with leaves and brown seeds used in cooking and medicine. According to one source, this substance is a staple in ancient Chinese and Ayurvedic medicines to induce labor, improve digestion, reduce skin irritation, and promote wellness. Positive blood sugar, blood pressure, and waist circumference benefits have been documented. The rich source of iron, protein, and plant components, including flavonoids and saponins in fenugreek, has been linked to hair growth. Another source claims this ingredient can ease scalp-related issues like dryness and thinning hair while hydrating and restoring luster and gloss.

Uttwiler Spälauber

Uttwiler Spälauber is a stem cell generated from a rare Swiss apple species. It is high in phytonutrients, proteins, and long-living cells, which promote storability and longevity. As for its contribution to hair health, Uttwiler Spälauber has been shown to increase the length of hair follicles for 18 consecutive days, increase hair density, and reduce hair loss. Moreover, it showed age-delaying effects on isolated hair follicles and maintained the dermal stem cell characteristics and regenerative potential of keratinocytes in hair follicles.


Niacinamide, often vitamin B3, is a water-soluble dietary element in fat-burning, oxidation, and reduction reactions. It also promotes hair growth by increasing blood circulation. The latter must be emphasized because enhanced circulation naturally increases oxygen delivery to hair follicles, increasing hair growth. Aside from blood circulation, this ingredient promotes scalp health by balancing moisture, reducing scalp inflammation (and the associated irritation), and supporting follicular cells, which preserve hair luster, body, and overall strength.


Zinc is a mineral critical for immune function, DNA synthesis, wound healing, and hair health. Specifically, a deficiency in this nutrient has been linked to hair loss. Does this mean a replenishment will have a reverse effect, you ask? More studies are still needed on this front. We know that zinc might inhibit 5-alpha-reductase, an enzyme liable for producing the DHT hormone (which shortens the hair growth stage) linked with female and male pattern baldness.

Serenoa Repens

Serenoa repens, or saw palmetto, is a supplement used to treat enlarged prostate, improve urinary function, increase libido and fertility, and reduce inflammation. This ingredient also plays a significant role in hair health. It may prevent male and female pattern baldness by preventing 5-alpha-reductase from turning testosterone into DHT, which, as previously stated, causes thin hair strands.


Biotin is a B vitamin and protein thought to help with hair growth (by increasing keratin production) in people with hair thinning or loss. Some studies have proven biotin’s effects on hair include improving hair volume, promoting scalp coverage, and maintaining hair thickness. Are these reasonable outcomes? More research is needed because biotin is frequently combined with zinc and iron, two nutrients associated with hair health.

Final Verdict on Our Re-Nourish Review

The above analysis should clarify that Re-Nourish renourishes hair follicles for healthy hair regrowth, new growth, incredible thickness, and shine. Seeing that the chosen ingredients contribute to the stated objectives is reassuring. Our research suggests that many improve circulation in the scalp for maximum oxygen delivery to hair follicles, increase time spent in the growth stage rather than the shedding stage and block enzymes that cause harm to hair health.

Though research for some ingredients is more limited than others, the overall results are positive, providing value to Re-Nourish. It’s also great to note that an anti-aging and hair health veteran created the serum with over three decades of experience. In light of everything discussed thus far, affordability is debatable, given that a 30-day trial costs close to $100. However, results are rated as quite reachable, so is it truly worthwhile? This is something that needs more consideration on a personal level. To learn more about Re-Nourish, visit here! >>>.
