Specifically formulated for men and women


DHT Halting Technology® is a proprietary blend of extracts, amino acids, oils, and nutrients to dramatically help fight hair loss, reverse hair thinning and encourage healthy hair growth.

  • Saw Palmetto: Multiple studies establish saw palmetto’s ability to encourage optimal hair growth by targeting DHT, the main culprit of genetic hair loss.
  • Biotin: An essential B-vitamin that promotes healthy hair growth and overall hair health. This ingredient strengthens both the hair follicle and the hair shaft, from which the hair grows.
  • Pumpkin Seed Extract: Studies establish that pumpkin seed extract stimulates healthy hair growth by suppressing the harmful effects of DHT and increasing circulation to the scalp.
  • Caffeine: Studies establish that caffeine stimulates hair follicles to grow thicker and stronger hair.
  • Green Tea Extract: Studies establish that green tea extract is rich in polyphenols. Polyphenols stimulate hair follicles, improve hair anchoring and promote stronger, healthier looking hair.
  • Black Cumin Oil: Black seed oil is rich in antioxidants and fatty acids that can strengthen the hair and improve scalp health.
  • Keratin, Hydrolyzed Collagen and Caprylic Triglyceride: Dramatically maximizes the thick appearance of your hair.
  • Vitamin C, Vitamin E, Sunflower Seed Oil, Argan Oil and Jojoba Seed Oil: Provide intense nourishment to your hair, noticeably improving the strength, natural shine and vibrancy of your hair.
  • Pisum Sativum (Pea) Extract: Studies establish that this extract contains a high concentration of isoflavones that positively influences the appearance of healthier and thicker looking hair.
  • Ginseng: Studies establish that ginseng can stimulate hair growth and prevent hair loss by inducing the anagen and delaying of catagen phases of the hair growth cycle.

Directions for use

The Maximum Hair Thickening Serum can be used daily as a styling agent for both men and women experiencing hair loss and thinning.

Thoroughly cleanse the scalp, then apply Maximum Hair Thickening Serum while the scalp is still damp so the formula is not absorbed by the dry hair shaft.

Fill approximately one-half (1/2) of the dropper with the Serum.

Apply a small amount of the Serum directly to the root of the hair in the areas of hair loss or thinning. It is not necessary to saturate your entire scalp with Serum.

Lightly massage the Serum into your scalp. Then proceed to style your hair as usual.

Do not rinse the Maximum Hair Thickening Serum out for at least 4 hours.
