the subject matter of embodiments of the invention disclosed herein is described with specificity to meet statutory requirements . however , the description itself is not intended to limit the scope of this patent . rather , the inventors have contemplated that the claimed subject matter might also be embodied in other ways , to include different steps or combinations of steps similar to the ones described in this document , in conjunction with other technologies . moreover , although the term “ step ” is used herein to connote different elements of methods employed , the term should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described . with reference to the drawings , and , in particular , to fig1 , a flow chart is presented that depicts an illustrative method of treating hair loss . as the term is used herein , “ treating ” can include any level of treating ( e . g ., partially treating , completely treating , maintaining a status quo associated with a condition , etc . ), any level of preventing ( e . g ., partially preventing , completely preventing , preventing a change in a status quo associated with a condition , etc . ), or any combination thereof . additionally , it should be understood that any number of additional steps and any number of variations on the steps described herein can be utilized in various embodiments of the invention . at a first illustrative step , step 102 , a hair - loss patient uses a sensitization kit . the sensitization kit facilitates sensitization of the immune system response , thereby increasing effectiveness of the overall hair loss treatment method . according to various embodiments of the invention , the sensitization kit includes one or more doses at different and graduated concentration levels of a sensitization mixture . the sensitization mixture includes urushiol . in some embodiments , the sensitization kit includes one dose of the sensitization mixture , while , in other embodiments , the sensitization kit includes a number of doses of the sensitization mixture . in some kits each dose of the sensitization mixture may vary from one or more of the others in the level ( increase or decrease ) of urushiol it contains ; in others the doses are all uniform but may be applied in combination to determine the appropriate dosage to obtain sensitization . according to various embodiments of the invention , an illustrative sensitization kit can include a number of graduated doses of the sensitization mixture . as the term is used herein , “ graduated doses ” refers to doses that increase in size ( e . g ., volume of the sensitization mixture associated with the dose ), strength ( e . g ., concentration of urushiol contained within the dose ), or a combination of size and strength . in embodiments , for example , each graduated dose of the sensitization mixture can include a different ( e . g ., increasing ) amount of the sensitization mixture . in other embodiments , each dose of the sensitization mixture can include a different ( e . g ., increasing ) amount of urushiol ( in which case , each dose can , but does not necessarily , include the same volume of sensitization mixture , but with different concentrations of urushiol ). in further embodiments , multiple doses in a sensitization kit can include the same amount of sensitization mixture and / or urushiol . any number of combinations or variations of the above also are contemplated as being within the ambit of the present invention . the dosages are typically applied in ascending order to determine the sensitization level of the individual . the epidermis may be scored before application if desired . embodiments of the sensitization mixture can include extracted urushiol , engineered urushiol , or a combination of extracted urushiol and engineered urushiol . extracted urushiol is urushiol that is extracted from a natural source . extracted urushiol can include urushiol extracted from any natural source or combination of natural sources . natural sources of urushiol include , but are not limited to , plants of the toxicodendron genus ( e . g ., poison ivy , poison oak , poison sumac , etc . ), plants in the anacardiaceae family ( e . g ., mango , rengas tree , burmese lacquer tree , india marking nut tree , cashew nut tree , etc . ), and other plants such as , for example , ginkgo biloba . engineered urushiol is urushiol that is engineered , rather than extracted from a natural source . in various embodiments , engineered urushiol can be optimized ( i . e ., the effectiveness of the engineered urushiol can be enhanced or selected to lengthen or shorten the period when the skin is in a sensitized state ) by the pattern of dosages employed , and the carrier with which the urushiol is mixed . engineered urushiols may be included in the sensitization mixtures according to embodiments of the invention , the sensitization mixtures can include one or more other chemical agents in addition to urushiol ( natural or engineered ) such as , for example , dinitrochlorobenzene ( dncb ), diphenylcyclopropenone ( dpcp ), or sadbe . additionally , in embodiments , the sensitization kit can include other chemical agents to be applied by the hair loss patient such as , for example , corticosteroids , androgenic receptor antagonist agents , caffeine , ketoconazole , dihydrotestosterone inhibiting agents , thyroid hormones , prostaglandins or the like . in some embodiments , the sensitization mixture can include any one or more of these additional chemical agents , while , in other embodiments , any one or more of these chemical agents can be applied independently of the sensitization mixture , as part of the sensitization kit . in various embodiments , the sensitization mixture and / or other chemical agents can be integrated with any number of various application mechanisms such as , for example , alcohol , acetone , aqueous or other solvent delivery systems , wipes ( e . g ., pre - moistened wipes ), cream , lotion , powder , gel , or the like . in an embodiment , for example , the sensitization mixture is applied using a roll - on applicator . in another embodiment , for example , the sensitization mixture is applied using a spill - proof blotter applicator . in embodiments , the applicators and other containers described herein can be equipped with child - resistant lids or other safety devices . similarly , the chemical agents employed in the various mixtures described herein can include taste bitterants , fragrances , and the like . it should be understood that the sensitization kit and mixture , as well as the re - growth 104 and maintenance kits 106 , can include any or all of these additional items and features to facilitate effectiveness , safety , and the like . for example , in some embodiments , the sensitization kit includes sterile sandpaper packets or sticks for scoring the epidermis prior to application of chemical agents . these may continue to be used during growth and maintenance phases . this engineered urushiol and sadbe , and or other commonly used contact dermatitis agents mixture , is hereby introduced as a poly - haptenol mixture employed in the sensitization kit . after sensitization occurs , and the sensitization dosage level is determined , a subsequent treatment referred to at fig1 as use of the growth kit ( 104 ) comprising application of a growth - enhancing mixture is employed . preferably , the growth kit includes a growth mixture comprising at least one and preferably a mixture of thyroid hormones t3 , t4 , t1a and t0a and other hormones such as prostaglandins and prostaglandin analogs in addition to urushiol at or near the sensitization level determined previously . the growth mixture is applied topically directly to the papilla and follicle increasing papilla vigor and size . this is the growth kit 104 . it is designed to rapidly initiate growth after the sensitization phase has rendered the immune system attack on the hair follicles ineffective . the growth - enhancing mixture may include multiple doses to be applied at scheduled intervals . the doses may be the same , graduated , or may be varied , all as related to the level of thyroid hormone or hormones . the doses or some of the doses may include urushiol and the same or varied levels or at or near the sensitization leve determined previously . the growth kit may direct the user to apply the doses in predetermined order or to change from one dose to another based on one or more physical results . lastly , a maintenance kit 106 for longer term use to maintain the results produced from the initial treatment is used . fig1 ( 106 ). the maintenance kit may contain multiple doses of a maintenance mixture . the maintenance mixture may comprise one or more thyroid hormones , prostaglandins or urushiol , or two or more hormones . the relative levels of hormones or urushiol or both may differ from dose to dose or be uniform , and the kit may include a recommended order of doses to accomplish a pattern intended to maintain the hair growth . alternatively , the kit may include description ( s ) of one or more physical results . if the maintenance kit seems to lose its effect for inducing hair regrowth , the method may be re - applied in its entirety , or partially . the growth kit may be employed ; or the sensitization kit may be used again , partially or entirely , depending on its effects , to re - determine a sensitization level . the topical doses of thyroid and other hormones employed by the kits and the method as a whole are considered non - therapeutic surface doses because they are only delivering a non - therapeutic amount of thyroid hormone systemically to the blood and a therapeutic dose directly to the papilla . papilla and follicular response to thyroid hormone treatment increases the size and vigor of the papilla and follicle in rats and mice . in order to dramatically increase alopecia treatment success , the first phase of treatment , referred to as sensitization , must be optimized . although it is possible to simply start with a growth kit that includes a dose that causes sensitivity in many people and this invention includes such an embodiment , the proposed optimization includes providing a graduated dosage sensitization kit including multiple chemicals , some of which may be engineered , to facilitate the sensitization reaction necessary for hair regrowth to start . it is believed that determining the sensitization level for the user may provide a better likelihood of getting results from the least possible exposure . once regrowth starts , the optional second phase ( growth ) of treatment can begin . this phase includes continued polyhaptenol sensitization and papilla / follicular growth stimulation by a hormone or a mixture of triiodothyronine t3 , thyroxine t4 , iodothyronamine ( t1a ) and thyronamine ( t0a ) prostaglandins and prostaglandin analogs . once hair regrowth starts and papilla size and vigor are increased to sufficient levels , a maintenance kit can be used which contains the same items found in the sensitization and growth kits but provides a schedule and dosages consistent with maintaining hair growth . the present invention has been described in relation to particular embodiments , which are intended in all respects to be illustrative rather than restrictive . alternative embodiments will become apparent to those of ordinary skill in the art to which the present invention pertains without departing from its scope . from the foregoing , it will be seen that this invention is one well adapted to attain all the ends and objects set forth above , together with other advantages which are obvious and inherent to the system and method . it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations . this is contemplated by and is within the scope of the claims .
a hair regrowth system consisting of sensitization , growth , and maintenance kits for alopecia areata and related alopecia balding conditions . graduated doses of specific engineered and or extracted haptens are included in a sensitization kit for initiating immune system response in hairless areas . a growth kit containing topical hormones to increase papilla size and vigor and a maintenance kit to sustain immune system response and papilla size and vigor for the long term are included in some embodiments .
