Definitions

  • the present invention relates to the treatment and prevention of human or animal alopecia conditions.
  • baldness is hereditary and occurs when the hair follicles slowly begin to produce finer and shorter hairs, or stop producing hairs at all.
  • hair loss There are many forms of hair loss, ranging from alopecia areata to androgenic alopecia, also known as male or female pattern baldness.
  • alopecia can remain as a permanent condition.
  • animals can also suffer from a variety of dermatologic conditions.
  • Such conditions frequently cause stress to the animal's haircoat resulting in hair loss, which further exacerbates an increased health risk to the animal and increased concern to the pet owner.
  • Common examples of dermatologic conditions of animals, which can result in hair loss include sebaceous adenitis, primary seborrhea, primary idiopathic seborrhea, seasonal alopecia, and other miscellaneous dermatoses.
  • Alopecia has many possible causes, such as genetic disorders, infections, contact with toxic agents, and hormone imbalance.
  • drugs approved by the Food and Drug Administration to treat alopecia there are only two drugs approved by the Food and Drug Administration to treat alopecia.
  • Rogaine ® also known as minoxidil
  • minoxidil was originally developed as a treatment for individuals with high blood pressure. While treating those individuals, it was discovered that minoxidil also moderately increased hair growth and prevented future hair loss. It is believed that minoxidil may increase hair growth in the thinning hair area.
  • the other approved product to treat alopecia is Propecia ® , or finasteride.
  • Propecia ® originally was used to treat prostate enlargement by inhibiting the 5-alpha reductase enzyme. Men undergoing that treatment experienced an increase in hair growth while receiving finasteride. It is believed that the inhibition of the 5-alpha reductase enzyme may increase hair follicle growth or prevent future hair follicle loss. However, pregnant or nursing women may not use finasteride because the product is teratogenic, and can harm the human fetus. Due to such a serious health risk, Propecia ® has been limited to use within male patient populations only, leaving a majority of female alopecia sufferers to seek alternative treatment options. Because of the downfalls of currently approved drug therapies for the treatment and prevention of human alopecia conditions, cosmetic treatments have been developed as well.
  • One cosmetic treatment as noted within U.S. Patent No. 4,999,187 to Nernon, discloses a hair and scalp treatment composition that comprises 60% by weight or more of petrolatum in combination with 5% by weight or more sulfur, 0.5% by weight or more of 1,2,3 - propanetriol, and the remaining 0.5 to 10% of the composition comprised of an oil, such as coconut oil.
  • the composition is said to treat the hair and scalp to effectively prevent dandruff in the hair while conditioning and causing the hair to grow in areas of the scalp where it had previously ceased to grow.
  • the '187 patent does not disclose the use of its composition for a variety of alopecia conditions such as alopecia areata. Rather, the ' 187 patent merely addresses the conditioning of the hair and scalp.
  • the first of those surgical methods includes hair grafts, in which a graft of a small area of hair bearing scalp is moved from one area of the head to another. Alopecia or bald areas are replaced with hair bearing scalp tissue grafts to allow for development of new, natural hair in the transplanted area.
  • hair grafts in which a graft of a small area of hair bearing scalp is moved from one area of the head to another.
  • Alopecia or bald areas are replaced with hair bearing scalp tissue grafts to allow for development of new, natural hair in the transplanted area.
  • hair flap is the hair flap, in which a piece of scalp along with its blood supply is moved from one location on the head to another.
  • This method generally is used only when large areas of hair bearing scalp need to be moved, and the procedure involves a lengthy recovery time. For those seeking a less invasive and shorter recovery time, excision or scalp reduction has been developed. Excision or scalp reduction involves removing the hairless scalp tissue areas and stretching the remaining non-hairless scalp to cover the defect.
  • the patient is subjected to a surgical procedure with its inherent risks and complications.
  • the last cosmetic surgical treatment method for hair loss involves tissue expansion, in which small balloons are placed beneath the hair bearing scalp, and the balloons are then expanded slowly over several weeks to stretch the adjacent area of the scalp intended to be used to cover the defect.
  • This method again, has surgical risks and complications including scarring, as well as a lengthier treatment and recovery period due to the length of time needed to stretch the existing scalp tissue and for the incisions to heal.

  • a typical hair comprises of hair shaft 1, which is rooted under the scalp, via dermal papilla 10 attached to hair bulb 9 which is a part of hair follicle 15, as seen in Fig. 2. Further, hair bulb 9 contains melanocyte cells 3 and keratinocyte cells 2 which help form and develop the various layers of hair shaft 1. As hair shaft 1 extends through an opening within the scalp or skin, it extends through external root sheath 7 and internal root sheath 8 which further helps to support and root hair shaft 1 within hair follicle 15 under the scalp or skin. As hair shaft 1 continues to grow, various layers develop, creating defined strata within the overall hair shaft 1. Those layers include an outer layer known as the cuticle layer 4 which surrounds cortex layer 5.
  • Both cuticle layer 4 and cortex layer 5 further surround an internal medulla layer 6.
  • Each of these layers develops from activity of the keratinocyte cells 2 and melanocyte cells 3 within hair bulb 9 of hair follicle 15.
  • the natural or structural shape of the distal end 14 of hair shaft 1 is pointed and closed to cause a tapering of the cuticle layer 4, cortex layer 5, and medulla layer 6.
  • the distal end 14 of hair shaft 1 will continue to remain tapered, such that its diameter will be less than proximal end 12. This can be further seen in Fig. 3. It is believed that this growth phase for hair follicle 15 to produce hair shaft 1 may last for a period of five years or longer.
  • distal end 14 of hair shaft 1 may lose its closed and pointed tapered shape through hair damage, such as cutting of the hair, or through other daily wear and tear activities that occur over time.
  • Fig. 4 illustrates this loss of tapering for distal end 14 of hair shaft 1 , such that the diameter of distal end 14 is equivalent or greater than proximal end 12.
  • cuticle layer 4, cortex layer 5, and medulla layer 6 at distal end 14 lose their closed and pointed shape creating a diameter and weight distribution which will become greater than that of proximal end 12 along hair shaft 1.
  • the entire hair shaft 1 may lose its natural shape, resulting in a decreased stimulation of keratinocyte cells 2 and melanocyte cells 3 within hair follicle 15 increasing the chance of hair loss due to this anatomical change and growth cell stimulation problem.
  • sealing and tapering along hair shaft 1 results in increased stimulation of keratinocyte cells 2 and melanocyte cells 3 within hair bulb 9 of hair follicle 15, such that cuticle layer 4, cortex layer 5, and medulla layer 6 continue to grow and taper, decreasing the chance of hair loss from scalp or skin 11.
  • the method and composition of the present invention reestablishes and lengthens the anagen/growth stage of hair.
  • the medulla layer grows at a faster rate than that of the cortex and cuticle layers, which further stimulates and rejuvenates dormant keratinocytes 2 and melanocytes 3 within the hair bulb 9 of the hair follicle 15 to increase production of the cortex and cuticle layers, resulting in an increased proximal end hair shaft diameter, lengthening of the hair shaft, tapering of the distal end of the hair shaft, and extension of the anagen or growth stage for the overall strand of hair.

  • the fusion and heated oil composition application steps are combined such that the fusion step is preferably completed before the heated oil composition application step.
  • the distal ends of the hair shafts are cut before the fusion step, such that at least the damaged portion of the hair shaft is removed. More preferably, the hair shafts are cut to a length of at least about l A to Vi of an inch from the scalp or skin to re-contour the cuticle, cortex, and medulla layers of the distal end of the hair shaft to a tapered shape.
