Summary of Significant Accounting Policies (Policies)	Mar. 31, 2017
Accounting Policies [Abstract]
Consolidation	Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates We prepare our consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (GAAP). In preparing these statements, we are required to use estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions. On an ongoing basis, we review our estimates, including those related to inventory valuation and obsolescence, sales returns, income taxes and tax valuation reserves, share-based compensation, and loss contingencies.
Translation of Foreign Currency Statements	Translation of Foreign Currency Statements A portion of the Company’s business operations occurs outside the United States. The local currency of each of the Company’s subsidiaries is generally its functional currency. All assets and liabilities are translated into U.S. dollars at exchange rates existing at the balance sheet dates, revenue and expenses are translated at weighted-average exchange rates and stockholders’ equity is recorded at historical exchange rates. The resulting foreign currency translation adjustments are recorded as a separate component of stockholders’ equity in the condensed consolidated balance sheets and as a component of comprehensive income. Transaction gains and losses and currency translation gains and losses on intercompany balances denominated in a foreign currency are included in other expense, net in the condensed consolidated statements of operations and comprehensive income.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company's subsidiaries enter into transactions with each other which may not be denominated in the respective subsidiaries' functional currencies. The Company seeks to reduce its exposure to fluctuations in foreign exchange rates through the use of derivatives. The Company does not use such derivative financial instruments for trading or speculative purposes. To hedge risks associated with the foreign-currency-denominated intercompany transactions, the Company entered into forward foreign exchange contracts which were settled in March 2017 and were not designated for hedge accounting.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers only its monetary liquid assets with original maturities of three months or less as cash and cash equivalents.
Concentration of Credit Risk	Concentration of Credit Risk Accounting guidance for financial instruments requires disclosure of significant concentrations of credit risk regardless of the degree of such risk. Financial instruments with significant credit risk include cash and investments.
Accounts Receivable	Accounts Receivable The Company’s accounts receivable as of March 31, 2017 and June 30, 2016 consist primarily of credit card receivables. Based on the Company’s verification process for customer credit cards and historical information available, management has determined that an allowance for doubtful accounts on credit card sales as of March 31, 2017 is not necessary.
Inventory	Inventories are carried and depicted above at the lower of cost or net realizable value, using the first-in, first-out method
Revenue Recognition	Revenue Recognition The Company ships the majority of its product directly to the consumer and receives substantially all payment for these sales in the form of credit card receipts. Revenue from direct product sales to customers is recognized upon shipment when passage of title and risk of loss occurs. Estimated returns are recorded when product is shipped. Subject to some exceptions based on local regulations, the Company’s return policy is to provide a full refund for product returned within 30 days if the returned product is unopened or defective. After 30 days, the Company generally does not issue refunds to direct sales customers for returned product. The Company allows terminating distributors to return up to 30% of unopened, unexpired product that they have purchased within the prior twelve months for a full refund, less a 10% restocking fee. The Company establishes the returns reserve based on historical experience. The returns reserve is evaluated on a quarterly basis.
Shipping and Handling	Shipping and Handling Shipping and handling costs associated with inbound freight and freight out to customers, including independent distributors, are included in cost of sales. Shipping and handling fees charged to customers are included in sales.
Research and Development Costs	Research and Development Costs The Company expenses all costs related to research and development activities as incurred.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes stock-based compensation by measuring the cost of services to be rendered based on the grant date fair value of the equity award. The Company recognizes stock-based compensation, net of any estimated forfeitures, over the period an employee is required to provide service in exchange for the award, generally referred to as the requisite service period. For awards with market-based performance conditions, the cost of the awards is recognized as the requisite service is rendered by employees, regardless of when, if ever, the market-based performance conditions are satisfied. The Black-Scholes option pricing model is used to estimate the fair value of stock options. The determination of the fair value of stock options is affected by the Company's stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. The Company uses historical volatility as the expected volatility assumption required in the Black-Scholes model. The Company utilizes a simplified method for estimating the expected life of the options. The Company uses this method because it believes that it provides a better estimate than the Company’s historical data as post vesting exercises have been limited. The risk-free interest rate assumption is based on observed interest rates appropriate for the expected terms of the stock options. The fair value of restricted stock grants is based on the closing market price of the Company's stock on the date of grant less the Company's expected dividend yield. The fair value of performance stock units that include market-based performance conditions is based on the closing market price of the Company's stock on the date of grant less the Company's expected dividend yield, with further adjustments made to reflect the market conditions that must be satisfied in order for the units to vest by using a Monte-Carlo simulation model. Key assumptions for the Monte-Carlo simulation model include the risk-free rate, expected volatility, expected dividends and the correlation coefficient. The fair value of cash-settled performance-based awards, accounted for as liabilities, is remeasured at the end of each reporting period and is based on the closing market price of the Company’s stock on the last day of the reporting period. The Company recognizes compensation costs for awards with performance conditions when it concludes it is probable that the performance conditions will be achieved. The Company reassesses the probability of vesting at each balance sheet date and adjusts compensation costs accordingly.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using statutory tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in income in the period that includes the effective date of the change.
Income Per Share	Income Per Share Basic income per common share is computed by dividing the net income by the weighted-average number of common shares outstanding during the period, less unvested restricted stock awards. Diluted income per common share is computed by dividing net income by the weighted-average common shares and potentially dilutive common share equivalents using the treasury stock method.
Segment Information	Segment Information The Company operates in a single operating segment by selling products to an international network of independent distributors that operates in an integrated manner from market to market. Commissions and incentives expenses are the Company’s largest expense comprised of the commissions paid to its independent distributors. The Company manages its business primarily by managing its international network of independent distributors. The Company does not use profitability reports on a regional or divisional basis for making business decisions. However, the Company does report revenue in two geographic regions: the Americas region and the Asia/Pacific & Europe region.
Effect of New Accounting Pronouncements	Effect of New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration it expects to receive in exchange for those goods or services. ASC 606 will be effective for the Company in the first quarter of fiscal 2019. The Company has performed a detailed analysis and does not anticipate that ASC 606 will have a significant impact on revenue recognition or its consolidated financial statements due to the types of revenue transactions that the Company enters into. Subsequent to the release of the updated revenue recognition standard discussed above, FASB issued Accounting Standards Update (ASU) 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815), ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients and ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. These updates are intended to improve the operability and understandability of the implementation guidance for the updated revenue standard as it relates to the subjects noted. The amendments in these updates have the same effective date as ASC 606 as noted above, and the Company does not anticipate that these updates will have a significant impact on its revenue recognition policy or its consolidated financial statements. In November 2015, FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Current GAAP requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. To simplify the presentation of deferred income taxes, the amendments in this update require that all deferred tax assets or liabilities be classified as noncurrent in the classified statement of financial position. The Company early adopted this update prospectively during the first quarter of fiscal 2017, which resulted in the reclassification of the deferred taxes from current to noncurrent on the balance sheet. Prior period balances were not retrospectively adjusted. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 841). For lessees, the amendments in this update require that for all leases not considered to be short term, a company recognize both a lease liability and right-of-use asset on its balance sheet, representing the obligation to make payments and the right to use or control the use of a specified asset for the lease term. The amendments in this update are effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods. The Company is currently evaluating the impact that this amendment will have on its consolidated financial statements. In March 2016, FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in this update involve several aspects of the accounting for share-based compensation transactions, including the income tax consequences, forfeitures, statutory withholding requirements and cash flow classification for applicable transactions, in an effort to reduce costs and complexity associated with these transactions while maintaining the usefulness of financial information. Prior to this update, all excess tax benefits were recognized in additional paid in capital ("APIC") and accumulated in an APIC pool and any tax deficiencies realized were offset against the APIC pool to the extent available, with any excess amounts recognized in the income statement. Under this new amendment, any excess tax benefits or deficiencies resulting from the exercise, vesting or settlement of share-based payment transactions will be recognized in the income statement as tax benefits or expenses prospectively from the date of adoption. Estimating forfeitures as part of the recognition of compensation costs is no longer required, rather, an entity can make the election to account for forfeitures when they occur. The Company early adopted this update during the first quarter of fiscal 2017 and began recording the excess tax benefits to the income statement. The Company elected to continue estimating forfeitures as part of its share-based compensation accounting policy.
