When To Use


Key Ingredients

Saw palmetto (Serenoa serrulata) extract is harvested from the berries of a palm-like plant. Though not as effective as prescription hair loss medications (finasteride and minoxidil), research shows that saw palmetto may help slow or stop hair loss by inhibiting the effects of DHT, the hormone most associated with male-pattern baldness.

Pumpkin (Cucurbita pepo) seed oil contains phytosterols, a plant version of cholesterol that’s been associated with hair growth. It’s thought that phytosterols block enzymes and hormones in the scalp associated with hair loss (such as DHT).

Curcumin, derived from turmeric root (Curcuma Longa) extract, has been shown in preclinical trials to lower levels of DHT by blocking the action of the alpha-5 reductase enzyme. Curcumin also acts as antioxidant and anti-inflammatory and may also increase blood flow to the hair follicle.  

Caffeine derived from coffee has been shown to help stimulate hair growth and halt hair loss by blocking the effects of DHT in hair follicles. It’s also been associated with stimulating hair shaft elongation (resulting in longer, denser hair) and speeding up the hair growth cycle.

Frequently Asked Questions

Do I need to use the Thickening Shampoo and Thickening Conditioner to see results?

The products in our Feel Fuller Haircare Duo are formulated to work synergistically, so we recommend  using the Thickening Shampoo and Thickening Conditioner together for optimal results. However, all products can be used individually with your favorites at home. The Thickening Foam can also be added to your routine for further optimization.

How can I best use the Feel Fuller Haircare Duo?

We recommend cleansing with the Thickening Shampoo 2-3 times per week in the AM or PM and following with the Thickening Conditioner. You may wish to add the Thickening Foam for use on days that you don’t wash your hair. 

Is there fragrance added to the Feel Fuller Duo?

Yes. We included fragrance to improve the sensory experience of our products. We wanted to make sure that men and women equally enjoyed the experience, so we deliberately chose a gender-neutral, refreshing scent. The Feel Fuller Haircare Duo is still appropriate for sensitive skin types as confirmed by dermatologist-testing at an outside research facility. 

Is the Feel Fuller Haircare Duo a replacement for topical minoxidil or finasteride?

No. Though we carefully formulated our Feel Confident haircare line with ingredients that have been shown by research to help with hair health and assist hair growth, they are not a replacement for medical therapy. Rather, our products are complementary.

Can I combine products from other lines with products from the Feel Fuller Haircare Duo?

Our products play well with others and can of course be used with products from other lines. However, too many products applied all at once can lead to irritation and damage. We recommend our paired down Feel Confident haircare routine to minimize extraneous products that could cause irritation, undue damage, or weigh hair down.
