SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
Dec. 31, 2021
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 2022” refer to the fiscal year ending June 30, 2022.
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, 2021. 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 six months ended December 31, 2021 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending June 30, 2022. 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 CashRestricted 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 Wella 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 (income) expense, net within the Condensed Consolidated Statements of Operations (see Note 9—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 acquired assets and liabilities associated with acquisitions, 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 resulting from continuing changes in the economic environment 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 six months ended December 31, 2021 and 2020 was 16.0% and 68.2%, respectively, and 25.1% and 156.9%, respectively. The positive effective tax rate for the six months ended December 31, 2021 results from reporting income before taxes and a provision for income taxes. The positive effective tax rate for the six months ended December 31, 2020 results from reporting losses before income taxes and a benefit for income taxes. The change in the effective tax rate for the three months ended December 31, 2021, as compared with the three months ended December 31, 2020, is primarily due to a benefit of $18.8 in the current period recognized on the revaluation of the Company's deferred tax assets due to a tax rate increase enacted in the Netherlands. The change in the effective tax rate for the six months ended December 31, 2021, as compared with the six months ended December 31, 2020, is primarily due to the limitation on the deductibility of executive stock compensation and large fair value gains related to the investment in the Wella business in the current period, as well as a benefit related to a change in the Company's main principal location of $220.5 recorded in the prior period. The benefit recorded in the prior period was the result of a tax rate differential on the deferred taxes recognized on the transfer of assets and liabilities, following the relocation of the Company's main principal location from Geneva to Amsterdam. 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, (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.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In January 2020, the FASB issued ASU No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815), which clarifies certain interactions between the accounting for equity securities, equity method investments, and certain derivative instruments. The Company adopted this guidance in the first quarter of fiscal 2022. The adoption of this standard did not have a material impact on the Company's financial position and its results of operations. Recently Issued Accounting Pronouncements In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new guidance under ASU No. 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is in the process of assessing the impact, if any, that ASU No. 2020-04 is expected to have on the Company’s financial position, its results of operations and related disclosures. In August 2020, the FASB issued ASU No. 2020-06, Debt- Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging- Contracts in Entity’s Own Equity (Subtopic 815-40), which removes certain separation models for convertible debt instruments and convertible preferred stock that require the separation of a convertible debt instrument into a debt component and an equity or derivative component. The guidance will be effective for the Company in fiscal 2023 on a full or modified retrospective basis, with early adoption permitted. The Company is evaluating the impact this guidance will have on the Company’s financial position, its results of operations and related disclosures.
Derivative Instruments	Foreign Exchange Risk Management 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. The Company is exposed to foreign currency exchange rate fluctuations in the normal course of business, including through exposure to inventory expenditures made by the Company’s international subsidiaries whose functional currency is other than the transaction currency. To manage this exposure, beginning in June 2021, the Company entered into non- deliverable forward foreign-exchange contracts (the “NDF contracts”) that are intended to offset changes in cash flow attributable to currency exchange movements. The NDF contracts have been designated as foreign exchange cash flow hedges. The Company entered into these contracts with counterparties that are banks or other financial institutions, and the Company considers the risk of non-performance by such counterparties not to be material. The Company also continued to use certain derivatives as economic hedges of foreign currency exposure on firm commitments, which do not qualify for hedge accounting. Although these derivatives were not designated for hedge accounting, the overall objective of mitigating foreign currency exposure is the same for all derivative instruments. The Company does not enter into derivative financial instruments for trading or speculative purposes, nor is the Company a party to leveraged derivatives. For derivatives not designated as hedging instruments, changes in fair value are recorded in the line item in the Condensed Consolidated Statements of Operations to which the derivative relates. Interest Rate RiskThe 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.
