Accounting Policies [Abstract]
Fiscal Period	The Company operates on a fiscal year basis with a year-end of June 30. Unless otherwise noted, any reference to a year preceded by the word “fiscal” refers to the fiscal year ended June 30 of that year. For example, references to “fiscal 2024” refer to the fiscal year ending June 30, 2024.
Basis of Presentation	Basis of Presentation The unaudited interim Condensed Consolidated Financial Statements are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and include the Company’s consolidated domestic and international subsidiaries. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these unaudited interim Condensed Consolidated Financial Statements and accompanying footnotes should be read in conjunction with the Company’s Consolidated Financial Statements as of and for the year ended June 30, 2023. In the opinion of management, all adjustments, of a normal recurring nature, considered necessary for a fair presentation have been included in the Condensed Consolidated Financial Statements. The results of operations for the three and nine months ended March 31, 2024 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending June 30, 2024. All dollar amounts (other than per share amounts) in the following discussion are in millions of United States (“U.S.”) dollars, unless otherwise indicated.
Restricted Cash	Restricted Cash Restricted cash represents funds that are not readily available for general purpose cash needs due to contractual limitations. Restricted cash is classified as a current or long-term asset based on the timing and nature of when or how the cash is expected to be used or when the restrictions are expected to lapse.Restricted cash is included as a component of Cash, cash equivalents and restricted cash in the Condensed Consolidated Statement of Cash Flows.
Equity Investments	Equity Investments The Company elected the fair value option to account for its investment in Rainbow JVCO LTD and subsidiaries (together, "Wella" or the “Wella Company”) to align with the Company’s strategy for this investment. The fair value is updated on a quarterly basis. The investment is classified within Level 3 in the fair value hierarchy because the Company estimates the fair value of the investment using a combination of the income approach, the market approach and private transactions, when applicable. Changes in the fair value of equity investment under the fair value option are recorded in Other expense (income), net within the Condensed Consolidated Statements of Operations (see Note 6—Equity Investments).
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. Significant accounting policies that contain subjective management estimates and assumptions include those related to revenue recognition, the net realizable value of inventory, the fair value of equity investments, the assessment of goodwill, other intangible assets and long-lived assets for impairment and income taxes. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and makes adjustments when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from those estimates and assumptions. Significant changes, if any, in those estimates and assumptions will be reflected in the Condensed Consolidated Financial Statements in future periods.
Tax Information	Tax Information The effective income tax rate for the three and nine months ended March 31, 2024 and 2023 was (158.8)% and 21.0%, respectively, and 34.3% and 22.1%, respectively. The effective tax rate of (158.8)% for the three months ended March 31, 2024 was primarily due to a benefit of $8.5 on the resolution of foreign uncertain tax positions compared to $3.4 of income in the period. The effective tax rate of 21.0% in the three months ended March 31, 2023 was increased due to a large limitation on the deductibility of executive stock compensation offset by large fair value gains related to the investment in the Wella business taxed at a rate below the statutory tax rate of 21% as well as a foreign exchange loss recognized on the repatriation of funds that were previously taxed. The effective tax rate of 34.3% in the nine months ended March 31, 2024 was driven up from the statutory tax rate of 21% due to an expense of $24.3 recognized in the current period on the revaluation of the Company's deferred tax liabilities due to a tax rate increase enacted in Switzerland, as well as the limitation on the deductibility of executive stock compensation. The effective tax rate of 22.1% in the nine months ended March 31, 2023 was increased from the statutory tax rate of 21% due to a large limitation on the deductibility of executive stock compensation. This increase was then offset by large fair value gains related to the investment in the Wella business taxed at a rate below the statutory tax rate of 21% as well as a foreign exchange loss recognized on repatriation of funds that were previously taxed. The effective income tax rates vary from the U.S. federal statutory rate of 21% due to the effect of (i) jurisdictions with different statutory rates, including impacts of rate changes, (ii) adjustments to the Company’s unrealized tax benefits (“UTBs”) and accrued interest, (iii) non-deductible expenses, (iv) audit settlements and (v) valuation allowance changes.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates, as well as additional disaggregation of taxes paid. The amendments in the ASU also remove disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for the Company in fiscal 2026. The amendments may be applied prospectively or retrospectively, and early adoption is permitted. The Company will adopt the standard and make the additional required disclosures beginning in the first quarter of fiscal 2026. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in the ASU require that a public entity discloses, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker ("CODM"), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. Annual disclosures are required for the Company in fiscal 2025. Interim disclosures are required for periods within fiscal years beginning in the first quarter of fiscal 2026. Retrospective application is required for all prior periods presented, and early adoption is permitted. The Company will adopt the standard and make the additional required disclosures beginning in the fourth quarter of fiscal 2025.
Derivative Instruments	Foreign Exchange Risk The Company is exposed to foreign currency exchange fluctuations through its global operations. The Company may reduce its exposure to fluctuations in the cash flows associated with changes in foreign exchange rates by creating offsetting positions through the use of derivative instruments and also by designating foreign currency denominated borrowings and cross-currency swaps as hedges of net investments in foreign subsidiaries. The Company expects that through hedging, any gain or loss on the derivative instruments would generally offset the expected increase or decrease in the value of the underlying forecasted transactions. Interest Rate Risk The Company is exposed to interest rate fluctuations related to its variable rate debt instruments. The Company may reduce its exposure to fluctuations in the cash flows associated with changes in the variable interest rates by entering into offsetting positions through the use of derivative instruments, such as interest rate swap contracts. The interest rate swap contracts result in recognizing a fixed interest rate for the portion of the Company’s variable rate debt that was hedged. This will reduce the negative and positive impact of increases in the variable rates over the term of the contracts. Hedge effectiveness of interest rate swap contracts is based on a long-haul hypothetical derivative methodology and includes all changes in value.
